Hi all,

I have had a terrible track record with keeping Cory. I have owned probably about 15-20 Corydoras Trilineatus in the last 2 years, and am now left with 2. They all kept dying from a mystery illness that didn't affect any of the other fish in the tank.

The remaining 2 are miserable and lonely. I want to get some more cory but there's no way I am buying Trils again. I have the opportunity to get hold of some Pygmy and some Salt and Pepper cory. My question is- will they group with the trils? The trils are much bigger than the salt & peppers and pygmies. Will the trills be happy if I introduce more cory of any species, or do they specifically need to be with other cory of the same species to be truly happy?

Thanks.

They'd rather be with their own species to be honest. But if you are really stuck other species will do, better with more corys of any type than just the two. I have a lonely cory which I actually saved from being nipped to death in the fish shop. I could never find the same species again as it turned out to be a rare one. It was behaving as a loner for a year in with a group of aeneus corys. Now he's quite part of the group and follows them, sleeps with them, etc.. It looks happy to me.

I'd be a little concerned about why your

Corydoras

keep dying, and I wouldn't buy any more until you had some idea of why they are dying. What are the symptoms of the mystery illness?

Could you give some details about the tank? Whether it is planted, what filtration you have, what the other occupants are, water change regime, what the substrate is, what you feed the fish etc.
