Hi everyone, little time no see, heh. Anyways, thought i'd do a quick thread on feeding your plec, as many people i have noticed only feed their plecs algae wafers/tablets, but in reality there is so much more to feeding plecs than just algae wafers- even for the algae eating plecs ;) .
The 4 main groups of plecs are the carnivorous ones, the alage eating/vegetarian ones, the omnivorous types and the wood eating types. To know your plec, you must not just know what type of plec it is, how big it grows and what its temperment is like, but what it eats- this seems obvious, but many people do not know what catagory their plec falls into exactly when it comes to food or feed their plec the foods it needs to be in full health often enough.
These are some of the foods that are accepted by most plecs;

High protein foods;
Mussels
Cockels
Prawns
Krill
Bloodworms
Catfish pelets

Vegetable based foods;
Algae wafers/tablets
Cucumber
Melon
Tomato
Spinache
...
......
Even the most vegetarian of plecs, will accept and need high protein foods of some type as they grow- common plecs for example, make very good algae eaters when they are little and can live entirely off vegetable based foods when young, but many types of veg or algae are very difficult to obtain enough protein off to give the plec the energy it needs to grow in life so it can reach its max size.
On top of that, the majority of the algae eating plecs sold will gradually go off algae as they mature, this is very true for the larger growing types of plecs like common and sailfin plecs. If you do not feed your algae eating plec any high protein foods, it is a good idea to start feeding them high protein foods after it is a 1/4 or a third grown towards its max size.
High protein foods aside though, veg is obviously a very important element to an algae eating plecs diet- once they have chowed down any algae in the tank that suits their diet, you will need to have to start suplimenting your plecs diet with at least algae wafers/tablets. In similar fashion to common livebearers with fish flakes, although most algae eating plecs can have the vegetable based part of their diet completely attended to by dropping in algae wafers for the plec to eat, for the best health in your plec you should also try and feed them fresh veg- any of the veg based foods in the above list are good for algae eating plecs.
You should try to feed your algae eating plec one sort of high protein food a week, although take into account the size of its sucker as it might be too big and clumsy to gobble up krill and bloodworms.

A good example of a vegetarian/algae eating plec is the Common Plec.

An omnivorus fish means it needs around a 50/50 veg and high protien based diet, although it is often more high protein based than veg based. The majority of omnivorous plecs will eat algae, but often make very poor algae eaters in comparsion to the more vegetarian based plecs- if you want a good algae eater for your tank, you are probably alot more better off with a small growing fish like oto's.
Either way though, a good mix of any of the foods in the above lists is important in attending your omnivorous plec's dietry needs :nod: .

A good example of an omnivourous plec is the Candy Striped Plec.

Ah...Carnivorous plecs...The majority of carnivorous plecs like the vast majority of other plecs, are not predatory, but rather just scavengers. Alot of carnivorous plecs though are very terotorial with other nocturnal catfish, and they can often find difficulty competeing for food if you house them in an active/semi agressive or agressive tank with fish that have a strong liking towards the meatier range of foods. "Ahem" anyhoo, this thread is not about pleco compatability or stocking but rather diet :*) .
Most true carnivorous plecs grow 8inchs+ and the majority will accept the high protein foods listed, although other high protein foods like chopped up earthworms or slices of fish, are also readily accepted by many. Like the vegetarian plecs though, the carnivorous plecs often suffer the same issues with lack of a particular type of food but the oposite- in this case, veg. A little bit of veg, like a little bit of high protein food in a vegetarian plecs diet, is very good to help balance out the high protein diet of the carnivorous plec :) .

A good example of a carnivorous plec is the Blizzard Cactus Plec.

Lastly, but not the least, are the wood eating types.
These fish vary a huge amount of what foods they need, so it is very important to do your own research like with all the other types of plec, but the main aspect of these types of plec's diet is wood. Having at least 2 types of wood in the tank for the plec to chew on is very important, preferably a peice of bogwood and a peice of driftwood, although the more types of wood you can get the better- thats basically the jist of it.

A good example of a wood eating plec is the Clown plec.

Of course there are many plecs that can over-step the boundarys of these clear food catagory types- for example, bristlenoses are primarily vegetarian plecs, but it is thought that elements in bogwood, particularly lignin, may form an essential part of the bristlenose diet- too much high protein based foods on the other hand, are linked to stomache disorders.


Anyhoo, hope you enjoyed this thread and if you have any comments or things to add, please post :thumbs: .
 
Thanks for that but i keep my plec's very happy.
Not so much of a varied diet of which i should have for them but plan to introduce more in time.
Cureently i feed them.

BloodWorm(Once a week)
Mussels (1 every 2 days)
Cucumber(Once a week)
Catfish pellets(One every two days)
 
This should be pinned. Another great one, Tokis! :cool: A subject that often gets forgotten about. I shall study it assiduously while planning for my 55 gallon.
 
ok so i just got a plec today. and that was some good info that you gave us. but the lady at the lfs told me that they will just eat everything off the bottom and they will be fine. wow i guess she was way off..
 
Thanks for the kind comments :) ! I have some more things though to add on this subject though.

As a rule of thumb in plec feeding, you should try to apply these no-no rules;

a. Never feed cereal products to plecs i.e bread or cereals; cereal products like wheat are not a natural part of any catfish's diet and they have not evolved to cope with digesting these products- this actually goes for most fish. Bread in itself is actually lethal to many fish as it can expand in their stomach and can cause severe stomach disorders like extreme constipation.

b. Do not feed foods that contain a high citric acid content i.e oranges and lemons; like bread, this can cause stomach problems as the vast majority of catfish are not designed to cope with digesting such foods with a high citric acid content- the majority of other fruits though like melons or tomatoes are very beneficial and do not have a high citric acid content. The other issue with high citric acid content foods is that they can mess with ph, and fast ph fluctuations are never a good thing for the fish involved.

c. Avoid foods with a high fat content i.e. pork or coldwater fish meat like goldfish meat- a tropical fish's body temp and metabolism is controlled by the temp of the water around it, so for tropical fish it is a very bad idea for them to put on fat as they'd overheat. Fat is not only difficult for the fish to digest, but can make them very ill especially in the long term- goldfish due to being coldwater fish, have a higher body fat content than tropical fish to help aid their survival through the cold winters, and although it is still not a high fat content, it is linked to stomach disorders and loss of max life expectancy in tropical fish if they are fed goldfish or other coldwater fish meat in the long term.
Goldfish also have a much thicker and more abundant slime coat than tropical fish for the same purposes as their higher fat content, and although most fish wont say "no" to another fish's protective slime coat, the slime coat is still a difficult thing to digest and also linked to health problems- this fact of feeding goldfish/coldwater fish to tropical fish actually applies to pretty much all carnivorous or predatory tropical fish out there.

And just one more thing: although this may seem obvious to most people as a no-no to food feeding, avoid feeding your plec or other fish for that matter, human sweets like chocolate or candy- these foods will lead to many health problems apart from just the E-numbers and sweeteners, the high sugar content is very unhealthy for fish (kinda applies to us to :p !).

A little note on high protein food feeding; Fresh high protein foods are beneficial for many plecs including other fish, but they are also known to play havoc with water quality- it takes very little time for meat to go off in an aquarium. So as a general rule, if you are feeding high protein foods to your plec, make sure any food left is removed within a day of entering the aquarium- it is also good to do a small water change afterwards if you can just to help keep the water fresh.
Rotting food in general is not only bad for water quality, but it can also harbour and grow nasty diseases like columnaris, so it is a good idea for any aquarium to make sure there is no old food in the tank and the substrate is kept clean on a regular basis to help prevent disease levels like the columnaris diseases rocketing and overcoming your fish's immune systems.

d. Fish and shellfish- often the best and healthiest high protein foods to feed fish are often fish and shellfish, but as previously noted on the subject of feeding coldwater fish like goldfish to tropical fish, not every type of sea or freshwater creature is healthy to feed to tropical fish.
As a general rule, if you are feeding your plec fish meat from the supermarket, make sure the fish is as fresh as it could be and not nearing its sell-by or best-before date, like most other things in a fish's life, fresh foods are often the key to keeping healthy fish.
As to shellfish though, if you cannot get hold of fresh shellfish like mussels or cockles, feeding a small quantity of shellfish pickled in a light brine water solution is fine- obviously avoid feeding shellfish though that have been pickled in vinegar or oil or other substances.
Another high protein food I forgot to add in the first set of notes though, is squid- this is also a good food for vegetarian plecs.

There is a 5th catagory of food type plec, and that is the insectivore plecs- i have no experience with keeping insectivore plecs, so i cannot give any personall experience with feeding them, but for the majority of insectivore plecs the insect part can be substituted with high protein critters like bloodworms and tubifex :thumbs: .
 
Excellent! Thanks! Of course, should be pinned...

Question: what is your attitude toward apple, potatoes, carrots?

My common likes apple (occassionally, as not pollute the tank too much); i never tried potatoes or carrots, but it seems that someone who would suck wood would also suck fleshy roots...
 
Excellent article, and I also like the idea of pinning this thread!

Another question: Would plecs enjoy grapes? Not sure about the amount of citric acid in grapes, would that be the decisive factor?
 
Sorry i didn't reply back earlier, ive been having some internet connection isues, anyhoo..
Im honestly not sure on potatoes and carrots...Im sure grapes and apples are fine as a treat but not as a regular food like cucumber as they contain alot of suger- once a week though should be fine :) .
Potatoes...Contain alot of starch, potassium and ascorbic acid; potatoes i am honestly not sure about, carrots contain alot of vitamin A, i think carrots would be alot safer and in comparison to potatoes as a pleco food because of their nutritional value and the nutritional values a vegetarian/common plec probably gets in its natural diet- i would advise though that they both be cooked before given as food though to help make them more digestable if you feed them to your plec :nod: .
 
You have really changed my plec's apatite,
I'll go out and buy all the other foods from my lfs
 
it seems that someone who would suck wood would also suck fleshy roots...

:lol:

I tried potato - no one touched it at all. Might try carrots though.... I also tried butternut squash, having seen one guys pic of about 6 of his babies chowing down on it, but my lot even started swimming like they were really freaked out by it, so I took it out. Wonder what it tastes like to them?? (btw, it was perfectly clean, no chemicals or pesticides etc, they just hated it being in the tank).
