Yeah, that's my little pygmy. ;0) I feel really bad that he's alone, unfortunately there are no stores that sell pygmy's around here... and some one from my Betta club just threw him in with an auction lot! He and my green girl swim around together.
Liz, it's really easy! I just syphon out the bottom every day, and do 50% WC's twice a week. It's yellow because I add lots of IAL, the 2 pairs are being conditioned right now. There's also a filter in there, just to keep the water flowing a little.
