Well, my sister just inherited a betta from a gal at her work who is moving. His name is Eugene. Eugene doesn't feel well, and I'm not sure exactly what the problem is. He spends most of his time between the filter and the back wall - almost like he is propping himself there. When he doesn't have that support, he sort of floats sideways. He is in (I think) a five gallon tank with a filter - no heater. There is a light on the tank. The water temp stays around 78 - 82 degrees farenheit (cooler in the evenings, warmer in the day time). He was the "office fish" for the past year and has never been super active. He eats teeny tiny little pellets. His previous caretaker would feed him 6-7 every night - no feeding on the weekends (since he was at the office and she was at home). My sister brought him home and feeds him 2 (sometimes 3) pellets each morning and each evening. He may have swim bladder issues (since he has a hard time staying vertical in the water), so we are trying to feed him peas. They sink. Before he has a chance to try to eat them. And he doesn't follow them down to eat them off the bottom. Also, he is so tiny (and his mouth is so tiny) that a piece of pea that is stuck on the end of a pin is almost too big for him. I suggested to my sister to mash up the peas and some fresh garlic (from my garden) and soak his pellets in the mixture. Then let the pellets dry so they will still float (when they were wet, they sank faster than the pieces of pea did). That seems to be working - the pellets soak up the pea and garlic juices, dry out and float just fine. Eugene loves them and eats them fine. Then goes back to hiding behind the filter. He still tips over when he is not supported. I do not have any photos of him at this point. He is at my sister's and she is having a hard time getting pictures. Any advice for us to try? He is a sweet little fish, and my sister keeps saying she doesn't want to have to tell her co-worker that Eugene didn't make it.
