well ive been trying to keep pygmy corys but ive had 3 out of 6 die in the last couple of days, they were really thin, i watch at feeding time and am convinced they are not getting enough to eat. between the other fish and shrimp the pygmys just arent competing. ive tried lots of different foods,ive tried feeding at night with lights off. do you guys think that regular corys would do better and if so what are some more active corys. would love gold line corys but i just cant find them.
