Ok, I am planning for my 250g tank and was wondering what type of cories I should get. I was thinking one of the larger liknds, I don't know what the names are, though. I don't like albino ones at all, they creep me out a bit. I was thinking about the Sterbai's but I don't know. There will be many very active fish in the tank with them, but nothing that will attack them. I want a fish that comes out, but is not overly active. What kind is best for me? I 'm planning on getting about 15-20 of whatever it is.
