Corys

[becca320]

Can anyone help , I am still having bother with my corys they are either a) gay b) boring or c) just plain and utter annoying
I have been trying to get them to spawn for ages, I have a Cory ONLY tank with about 4 different species ie / sterbai, peppered, albino and the other ones like peppered with the full black top fin (cant remember name) ... oh and a small bristlenose... they apsolutely point blank refuse to spawn and I really dont know where I am going wrong they are really doing my head in now ... I have lowered temp , fed them live food the works , I wondered if they may be eating any eggs i didnt notice ??
Any replies appreciated

LOL
The bristlenose will eat the cory eggs but the cories are unlikely to eat their own.
Have you treated your fishes for worms? Try deworming them and see if that makes a difference.
Feed them 2-3 times per day with frozen prawn, fish, squid, bloodworms, brineshrimp & daphnia.
Raise the temperature to about 26C.
Do massive daily water changes (75-80%). Make sure the new water is free of chlorine. A slight temperature drop from the water change will often stimulate the fish into breeding.
Make sure the fish are mature. Most cories won't breed until they are at least a year old.
Make sure you have males and females. When viewed from above males are slender, females are wider across the head and body region.

Right
Chasing bristlenose now all night , will put it in another tank and try the above..
I aint sure about sexing them , i cant tell ...
But they should all be mature enough
Honestly I think that corys were just put on this earth to annoy me , never ever had a fish species wind me up as much as these guys ... but I love em to bits ..
Thanks

Well what do you expect? How well would you perform if someone was constantly watching you?

My C. napoensis eat their eggs although I don't know if they only eat unfertilized/defective eggs. If yours stick them to the glass, you should be able to see residue from the 'sticky stuff'; it'll be clear but you should see a circular outline.

If you look at them from the top you should see a distinct difference between the males and females of the same species with the females being a bit longer and much wider than the males.

If they're uncomfortable with their surroundings they're less likely to lay eggs.

You'll know they're interested when they start cleaning potential egg laying sites and when the males start 'bugging' the female.

Good luck.

My experience has been the opposite. Corys will eat their eggs and I have watched a bristlenose eating algae on the glass go around cory eggs. This was not a full adult size bn, but it was a couple of inches and capable of eating the eggs.

As for getting them to spawn I suggest you try the following. Skip a weekly water change or two. Feed lots of high protein food- ie make sure there is always food availabe for the corys. Then try to time a large waterchange (at least 50%) to coincide with the arrival of a storm. You can add cooler water with the big change to drop the tank temp. I have never found that part to be nessesary and have never done it. However, if you want to, do it since many folks do feel it is important. If you decide to go with the lower temp change, unplug the tank heater and leave it unplugged for 4-6 hours.

Corydoras will eat their eggs, especially the species you listed. Peppered cories are known for eating their eggs.

As for them not spawning, it might be the fact that you dont have the right male/female ratio. The albino and peppered cories are among the easier species to spawn in the home aqaurium.

Like what Cory_Dad said, if they are not happy or are scared in their surroundings, they will most likley not spawn.

One thing you could try is put a group of the same species in their own tank and see what happens.

Good Luck

I have just taken another 3 x 3ft tanks, so I think I will try and seperate the species up, maybe with dividers, I am not too sure yet .. And dont have enough plug sockets in the garage or the space come to think of it ... will need to try and build some kind of frame to put them all in ???

Anyhow thanks for all the replies, hopefully they may get jiggy soon ...

I would concentrate on the albino, assuming they are C. aeneus. They are the easiest to spawn and once they start you will have babies non stop whether you help or not. Both peppers and sterbai are often egg eaters, well as the albino bronze. Not all Corys are devout egg eaters, but I sus[ect that the food they are offered can influence their egg eating. I have not seen any of my BN interested in Cory eggs--not to say they don't eat eggs, but they are one of the creatures that are recommended as tank mates for Cory breeding tanks.

I would apply what Barracuda and TwoTankAmin have suggested: Be sure you have male and female, be sure they are mature--a year old is fair for most species, separate the ones you are going to concentrate on, fast them a day or two and then feed them like kings and queens, when there is a major barometric weather disturbance do a fairly large cool water change, give them some quiet time undisturbed.

How about giving us an idea of their habitat, including the tank temp, ph, water change routine, water movement, stock level?
