Hi! I fell in love with a handsome dude - Mustard - and a friend of his - Catsup - at my favorite LFS today. I brought them home to put in a divided 5 gal. Mustard looks like he has spent too much time in the tiny cup. (WalMart uses bigger cups than this place does!) His fins seem to be clamped together, like he's been holding them close to his body because he hasn't had the space to spread them out in a long time. His body looks like it's in good shape. Is there anything I should be doing other than keeping his water crystal clear? He seems to be swimming happily around in his new digs. The divider in the tank is green; I don't think Mustard and Catsup and see each other.

Thanks!
Donna

Sounds like you are doing everything that needs to be done. IAL might help as well if you have some. Congrats on helping out the poor guys!
