Discus in general

Discus Cichlids have taken on the name ‘King of the Aquarium’ for many reasons, such as colour, shape & behaviour. First off, discus can come in many different colour morphs such as Pigeon blood, Red Turk, Blue Turk, Brilliant Turk, Diamond, Blue Diamond, Snakeskin, Marlboro Reds, Red Melons; just to name a few. I would be here all day if I were to write all about the colour morph varieties! Let’s just say, the possibilities of discus colour morphs are endless.


Discus with blue pigment show of their colours best when the aquarium has marine lights (14,000 K +). In planted aquariums, the Blue Turk looks fantastic, as it stands out through the green background of plants.

Now, their shape, as their name suggests, is like a discus: an almost circular appearance. The only cichlids which come close to the Discus body shape are Angels, Severums or the Uaru; however, these have slight differences in comparison to Discus in shape & colour. Their unique shape just adds to their striking appearance, making them even more attractive to fish keepers.

Note the discus-like shape. As Discus become more mature, they take on a more round appearance.

Behaviour: They are very friendly cichlids if kept in shoals of 5 or more (try to aim for odd numbers of discus in shoals as this spreads their aggression). You will not get bored of them swimming up and down the tank in unison, begging for food and exploring around the aquarium.

As Discus are one of the most spectacular cichlids in the world, yet they are not easy to care for nor affordable, but, if you follow my guidelines, you should have few problems. As Discus are becoming even more popular, many breeders allow you to purchase Discus’ at a reasonable price (£10.00-£20.00 for common colour morphs). Most illnesses/parasites are from poor water quality or introduced by new fish or food, so care should be taken.


Discus Details

Size: A healthy discus can reach as large as 9"; however, 6-8" is more common.
Tank Size: As a rule, two adult Discus (pair) should have at least a 30 gallon aquarium. Add at least 10 gallons for each additional Discus. The aquarium should be 16"+ in height, as they are deep-bodied fish. KEEPING ONLY ONE DISCUS WILL RESULT IN STRESS AND INEVITABLE DEATH.
PH: 6.0 -6.5 is needed for breeding. My Discus’ live in a Ph of 8.4!
GH: 2-11
KH: 1-6
dH: 0-3dH
Temperature: 25-29°C (77-84°F), 28C-31C when attempting to breed



Diet

Discus are carnivorous, so feed live/frozen foods such as: Blood worms, Glass worms, Beef heart, and Tubifex worms. Frozen foods that are high in protein are also ideal. For staple you can use Tetra Prima granules for Discus or Sera Discus granules. It should be around 50-60% granules and 40-50% frozen/live. I personally do not use live food as the live food purchased at my fish shops seem to always result in a fish developing an illness.



Habitat


Discus are found in planted and wooded areas in the slow moving backwaters of the Amazon River system. This water is soft, warm and has little current. They are found in large groups, except when spawning. Their natural food is a mixture of aquatic invertebrates, small fish, insects, and fry. Many other commonly kept South American tetras (such as the Cardinal Tetra) and cichlids can be found in these waters, which can make ideal tank mates. Their shape helps them slip between wooden branches and stems, and their colours provide camouflage by breaking up their outline and blending with the shadows.



How to feed


Feed your Discus at least 3x a day, varying in foods each time. You can feed them small amounts 5x daily, which should speed up their growth rate. Overfeeding will lead to deaths and stunting, so if you have doubts that you are not feeding your Discus the right amount, feed less! The myth of granules expanding (because they haven’t absorbed water when the Discus has consumed them) inside a Discus’ stomach, resulting in bloat, is a myth. Maybe if you are feeding your discus catfish pellets this might happen. It will not occur with the correct food, though.



Useful tips when Buying Discus

When looking at the fishes health, don’t just look at the Discus you have set your eye on, examine the other Discus/fish that are also in the tank. Chances are with Discus, if one is ill so are the rest of them.


The signs to look out for are:


•Stringy white feces
•Thin and pale Discus/fish
•Discus/fish with noticeable abbesses, fungus or ripped fins.
•Discus/fish gasping for air at the top of the water or laying on the bottom of the aquarium on their side.
•If they are in an aquarium with unacceptable tank mates (i.e. Silver dollars), chances are that they’re under a lot of stress and could have a parasitic infection.
•If you see a discus with a white area, with ‘white stuff’ hanging of it, is actually the Discus’ slime coat and it may have been damaged by another fish or even when it was caught. Either way, a damaged slime coat can lead to infection/disease, which leads to death.

•And anything you might think is unusual!



Filtration


There seems to be a bit of a controversy as to what is the best filtration for Discus. IMHO, sponge filters are the best when breeding/growing Discus, as they quickly collect beneficial bacteria and do a good job of purifying the water. As Discus eat loads of meaty foods and are a classic cichlid (messy), you should aim to at least x2 the tanks recommended filtration. In one of my discus aquariums I have a Bio life wet/dry filter. This keeps the water clean and the Discus happy. In my other aquarium (40 gallons), I have 2 sponge filters capable of filtering a 60 gallon tank and on top of that, I have a Magni jet (for up to a 55 gallon aquarium) Sponge filter, as I found that the two sponge filters were not capable of doing the job alone. So, aim for at least 2x your recommended filtration and just choose what filter is in your range. If you have got the money, aim for 10x biological filtration, then you will be able to do less water changes and spend more time watching your fish!



So my water is not acceptable for Discus, how do I lower the pH?

This pinned thread will explain it all-http://www.fishforums.net/So-You-Want-To-Alter-Your-Ph-t187893.html. Try to avoid most chemicals. Tank bred Discus won’t need to have a change in the waters pH, as the Discus will already be acclimatized to it. Tank bred Discus can be very hardy, unlike wild caught Discus, which can be susceptible to parasites and illnesses. As I have stated, my discus are in a Ph of around 8.4, although my decor (wood & plants) seems to lower it to around 7.8.


Maintenance


The more water changes and the more times you feed your Discus throughout the day (remember it’s not the quantity of the food, but the amount of times you feed them throughout the course of the day), the faster the growth. Feed at least 3xs daily. Change water (minimum) every 4 days for young discus, weekly (minimum) for sub adult Discus and every two weeks (minimum) for adults. If you see a large amount of waste build up on the bottom of the aquarium regularly, you should revise how much you are feeding, what your filtration and water change routine is and your stocking levels. Keep in mind that small waste that build ups on the bottom of the aquarium is common, but should also be sucked up with a siphon/python/gravel vac. Clean the filter media every 2 months in aquarium water, keeping the beneficial bacteria and ridding it of old waste. If using a RO (Reverse Osmosis) unit you will not need to add any chemicals to remove the chlorine/chloramines; however, if you are using tap water, you may want to test your chlorine/chloramines levels in your water. Adding water with a lot of chlorine/chloramines in can kill the good bacteria on filters, resulting in a mini cycle. You can buy commercial products which remove chlorine/chloramines for the water.

They should not be kept with fish which may try to suck their slime coat off, i.e. Common & Sailfin plecos (and others belonging to the Panque group), or other fast moving/fin nipping fish such as Tiger barbs and Blue Gouramis. Also, quarantine all fish for at least 3 weeks before introducing to your Discus aquarium. Please PM me if you have any other tank mates for Discus which are not on this list.



Angelfish: Good or Bad tank mates?


nmonks (registered user): The disease Hexamita, which is very common in commercially raised stocks of angelfish and some dwarf cichlids (esp. Mikrogeophagus ramirezi) can easily spread to Discus. Without antibiotics, it is very difficult to cure. Be sure to quarantine them in a separate aquarium for at least 3 weeks.



So I know what a Discus is and what requirements they need, but what tank set-up do they need?


There are three ways you can go.


1. Heavily planted aquarium with bogwood/Mopani (can help to get Discus less shy) roots. The only advantage you get from setting up a tank like this is the appearance and the fish which will love it; however, you must stop algae and maintain the plants while keeping a healthy environment for your Discus. If you want to set up an aquarium like this, I suggest you have a look through the pinned articles on the planted tank section of the forum.

2. Bare Bottom (no substrate). Usually used for growing young Discus or for breeding Discus. Advantages with this set up: can be easily cleaned, less or no algae issues and a much easier way to keep the water clean. You can use any of the normal decors and even potted plants such as the Amazon sword. IMO Amazon swords are a must, because Discus use these plants to rest on when sleeping.
3. Normal set up. Gravel/sand as substrate and Bogwood/Mopani roots (do not use rocks which may raise the pH) for decor. This kind of set up is quite easy to do, but as it will not have plants I doubt discus will like it much.


When setting up any Discus aquarium, you should make sure you include plenty of retreats (Mopani roots/plants), which provide cover and shade. These will make your Discus feel more secure.

Many people ask "Why are my Discus skittish?" Well, the most common reasons are:


1. You have not got enough retreats and decor to make your Discus feel safe. Add more retreats and hides such as mopani roots, bogwood & plants.
2. You only have a small shoal (under 5) of Discus, which will make them feel insecure. Have a minimum of 5 Discus. If you have a pair, they will be ok by themselves.
3. You have incompatible tank mates, which steal the food, spook or bully your Discus. Remove the tank mates.
4. High traffic area. If you have a tank where lots of things are going on (I.e. kitchen/lounge) they feel insecure because of all the vibrations and movements outside the aquarium. Move the aquarium to a room with less traffic.
5. Your aquarium has bright lights, which spook the Discus when you turn them on. Replace the lights with something more suited to Discus (say 1 WPG).


nmonks (registered user): The mistake people make with discus (and angelfish) is not to build the wood up to the waterline, and instead scatter it at the bottom where it's no good to the fish at all. What these species want is plenty of tall, tree trunk-like bogwood around which they can school and hide.



I've had my tank set up for a while now and I want to go the next step. How do you breed Discus?


To start of you will need a minimum of a 55gallon aquarium (keep it bare bottom so you can quickly remove waste) & 6 sub adult or adult Discus. For ideal conditions, your pH should be between 6.0-7.0, kH of 1-6, gH of 2-11, dH of 0-3. You will need to feed the parents a very good diet (as shown earlier). In time, you should notice that some Discus form pairs. Once this happens, separate the pair and place them in a minimum of a 30 gallon aquarium. Perform water changes every day or every second day. It is proven that Discus breeding & feeding responses are triggered when water changes are performed, because it simulates the changes in season in the Amazon River. Once your pair is established, they may lay eggs as many times as 15x a week! The eggs take roughly 2 days to hatch and become free swimmers another 3 days later. You will notice the fry stay to the parent’s side and eat their slime coat (for food). After they have been free swimming for 5 days, you can feed them brine shrimp. Remove the fry after 2-3 weeks, as the parents can become stressed and it is a risk to their health. Breeders recommend feeding 6x+ a day for hatchling Discus, as their appetite will be strong and this is the stage where they grow rapidly. Try to do water changes everyday after the last feeding on your rearing tanks. Then the processed is repeated!



Conclusion

Discus are fantastic fish and have definitely earned their name ‘King of the Aquarium.’ I have to admit they are definitely the most attractive fish I have (owning 8 of them myself). These fish are not for a first time hobbyist; however, any fish keeper who has enough knowledge to be able to run an aquarium (and keep the fish alive in it!) should have success with Discus. They are not as hard to care for as some people say, because if master your feeding and water changing routine, you will find these fish as easy to care for as any other fish (well maybe not any fish).

I hope you have found this information useful; however, it isn’t finished yet. I will get better pictures of my Discus (cleaning them tomorrow evening) and edit the information when I find mistakes. So if you have any advice, ideas or pictures please PM me and I will add them, of course giving the credit to you! Btw at the moment, I am still adding information. Once I have finished adding information, I will hand over to someone to edit. I need pictures from you guys for different colour morphs!

Thanks!

Pretty thorough article and, just for the sake of being hard on grammar, there are some slight mistakes and awkward sentences that need revision.

I agree with most of the tankmates, but I would like to point out that plecos are very risky with Discus, because they could possibly suck on the slime coats. Also, angels should not go with Discus, because they can host diseases that the Discus can not fight off. Other than that, pretty good.

EDIT: Isn't 30gls too small, even for a pair of Discus?

Would you PM me and underline them.On some bits i wasn't looknig at the screen and just typing so i know what you mean :blink: .Thanks :good:

Angels giving Discus diseases is a old myth which was going around the net 10 years ago and still is...
They should not be kept with fish which will try to suck their slime coat of (i.e. a large pleco)-do you think i should highlight this a bit more,incase you missed it?

EDIT: Isn't 30gls too small, even for a pair of Discus?
Actually i upped that buy 10 gals.A breeder who i bought all my Discus of kept them in 20 gallon aquariums,tthey were in fantastic condition
 
Mm, I agree invader, there's a few too many spelling/syntax errors for me to read this and not cringe. ^^" Sorry. If you'd like, I could correct it and then PM the corrected copy to you...?

Also, for someone like me who's rather new and unexposed to discus, I'd really love to see the colors and pictures of the discus matched up, perhaps even sorted in order of rarity and or price. I've seen such great variations in their prices as young juveniles, and I don't want to spend possibly $100 more then I needed to. Even descriptions of the main color morphs would be greatly appreciated.

:blink: 20g? Wouldn't their bottom side scrape against the ground at all times once full grown? And is it just 1 fish to each 20, or the pair?

Overall a lovely little thread; thank you muchly! :good:
 
superb post!!!

disagree with the clown loach`s and discus thou...

let me know if u need some pics

Thats a red turk in your avatar?If you send me one like that it will be helpful.I'm going to get more pics this afternoon.
 
Great article. I do agree about the problem with some plecos and discus. plecos have been known to suck on the sides of discus, especially ones in the Panque group. I have found that peckoltias and other small plecos are excellent tanks mates. Also beware of teh massive amounts of poop plecos will put in your tank. i had a flame pleco with my discuis that had tyo be removed because of its messy tendencies.
 
Pictures people! And any info which you think needs to be added.
 
the discus in my avtar is a leapord skin
 
I enjoyed reading it. As mentioned above, there are some typos, and the lack of spaces after commas is a bit annoying. I personally avoid using acronyms (e.g. PITA) in anything I publish -- why assume your reader uses your vernacular? Much safer not to.

Also, re: discus and plants. In the wild, Symphysodon spp. live in the flooded forest in particular the blackwater regions. In these places, aquatic plants are very uncommon. Instead, the discus congretate around tree trunks, sunken wood, and so on. Their shape helps them slip between wooden branches and stems, and their colours provide camouflage by breaking up their outline and blending with the shadows. So the "real" environment in an aquarium doesn't need plants, and the discus should be perfectly happy kept like that. The mistake people make with discus (and angelfish) is not to build the wood up to the waterline, and instead scatter it at the bottom where it's no good to the fish at all. What these species want is plenty of tall, tree trunk-like bogwood around which they can school and hide.

You might also want to mention that although tank-bred discus are relatively easy to care for, the wild-caught fish most certainly are not.

I've been told mixing angels with discus is bad not just because of bullying but because the diseases endemic to cheap angelfish farming practises "hop over" to discus very easily when the fish are in the same tank. It is also worth mentioning that the high temperatures discus need rules out some common tropical fish as tankmates, notably danios and some (subtropical) Corydoras such as Corydoras paleatus.

Cheers, Neale
 
Ok,thanks for that.I'll add that info now.I'm only 13 so my grammer sucks ,who wants to edit!? :good:

I don't mean to sound aggressive but this is all i'm hearing i've been told,somebody said,but i looked on the internet...The truth is they can be kept together,with care.
 
It's fine, you should always be critical about hearing things.

I'm hearing this not from hobbyists but from other professional fishkeeping writers. So I trust them. I believe the disease is Hexamita, which is very common in commercially raised stocks of angelfish and some dwarf cichlids (esp. Mikrogeophagus ramirezi). Without antibiotics, it is very difficult to cure.

In theory, angels and discus should get along very well (they like the same warm water, but please note that discus prefer very soft and acid water whereas angels are mostly found in slightly acidic to neutral water with low to moderate hardness, i.e., blackwater versus whitewater rivers). But I think the key thing is to mix them *after* quarantine, so that you can be absolutely sure that the angels (which are reared under intensive conditions to keep the price down) do not bring anything into your discus aquarium.

Angels also have (in my opinion) a higher level of agression, so it is important not to overcrowd them, especially not male or paired angelfish. So as you say, with care they can be kept together. But quarantining is probably essential for reliable success.

Cheers, Neale
