I just went to that website and read the requirements for it and my tank temp is almost at its cap at 78 degrees. I compared them to the pygmy Cory but I thought those were the same. It didn't say anything about pygmy Cory's being kept in shoals. So I'm a little confused.TexasDomer said:Cories are very active little guys and really should be kept in large groups (larger groups than endlers), hence the recommendation for a larger tank.
What dwarf cories are okay in 28 C? Planet Catfish, which is arguably the most accurate and reliable source of info for catfish, has their max temp much lower. I wouldn't keep bettas at 25 C. 26-28 C is ideal.
