Cory's for a 10 gallon

[Leopardess]

Research those emeralds a bit more. Some of those "True" emerald "cories" aren't a cory at all, but a very close cousin. They get a significant amount larger too. I have personally seen them at about 4-5" and the one I have now is at least 3."

The true emerald catfish are called "brochis splendens" I believe. here are some links, though a few of them say they do not get as large...but I have seen it and have found other sites that say they do. Some great pics though...But even at 3.5" they will be too large for a 10g.

Also, I have albinos, pandas, bronzes and emeralds in my 55, and they prefer to stick together in their own little groups, rather than schooling together.

Just to add to the topic of feeding cories, I would like to say that I feed mine the "Scraps" and they seem to thrive. By scraps I mean extra flakes that fall to the bottom of the tank...I purposely do this so they eat so I suppose its not scraps except that it does pass by the other fish (mainly livebearers).

...so while the fish certainly wont starve to death if you feed flake foods, do make sure to "push" some flakes down in the water so that they sink to the bottom, otherwise we cannot promise that your fish will be fed!
