He's been around for almost a year in my tank, and hangs around with my black ruby barbs. I love his long fu man chu barbels. He has been pooping like that for maybe a month and I have always fed him the same type of food. I feed him flake food, but it doesn't have a label and it come from this sweet old Japanese dude, who is probably around 80 years old. I think he makes it. He 's got a shop in korea town and I swear it looks like in the movie gremlins where he purchases the gizmo thing. Except with fish. Every time I go in, I'm thinking he is going to take me in the back and show me a three headed freshwater apisto/guppy seahorse. He is pretty sweet. Anyway I'm digressing. All the other fish are doing fine. I like the peas idea, i will give it a try. Peas usually just give me gas, so I hope the pandas tank mates don't mind a little panda tooting. Do fish pass gas anyway? Anyway thanks for the info i appreciate it.
