Breeding Groups for Corys, although groups of 3 have been succesful, should be of at least 6 of each species. The tank can be a standard 24x12x12, with a cool water temperature, a few plants, and sand substrate.

i have my albino and pepper corys in 2 20L moby dick tanks.
I have 10 albino and 9 pepper and i have had 4 spawns from the albinos in the past week !!
keep the temp around 26 and to force the spawning, do a 40% water change with condtioned cold water straight from your tap. It needs to be about 10 degree less than the tank temp.
works for me everytime

how many do you keep in a 20l tank?

10 albino in 1 and 9 peppers in the other (btw, make that 5 spawnings in 1 week 1 day from the albinos. woke up to another this morning!!)

ammonia 0 nitrite 0 nitrate 5ppm in both tanks.
nope. they are all quite happy and if they werent they wouldnt be spawing the way they are.

Hi lychas
Let me explain a bit what's going on here, so you understand why Sp00ky is successful despite what many people would consider overstocking.
The key to his success is in keeping the nitrate level low. As you probably know, the beneficial bacteria convert fish waste products first into Ammonia, then into Nitrite. These are both harmful to the fish until still other beneficial bacteria convert the Nitrite into Nitrate. But Nitrate is only harmless at low levels. When you keep a well stocked tank, full of fish who are eating well, the end result is that the Nitrate level can rise to unacceptable levels.
The way to manage a heavily stocked tank is to do large enough, and frequent enough, water changes to keep the nitrates down. Depending on the natural nitrate content in the tap water, and the number and size of the fish, this might mean doing water changes weekly, or it might even mean doing them daily. The important thing is that it is kept below 30-40 ppm. The lower it is, the better the corys will do.

elequantly put my good man !!
I would also like to mention that once i identify the main breeders, i will remove the others from the tank and place them in their own tank. I think someone needs to come up with a way of tagging fish.... painlessly of course LOL

Nitrates can go to 100ppm and higher before anything happens to fish. Lower is better but it's not essential.

Yes I stated lower is better but it doesn't matter much, unless you are going for marine's or especialy sensitive fish.
You are wrong about that, jayjay. High nitrates are one of the stress factors that can weaken a fish's immune system and make them more subject to bacterial infections. Since corys live at the bottom, where fish wastes and uneaten food may collect, with the result that harmful bacteria thrive, they are especially prone to bacterial infections. Every effort a fishkeeper makes to make the environment clean and safe for them will be worthwhile.
100 ppm of nitrate is totally out of line.
