Yeah they're in a10 gallon tub now and have been trying out new foods. They're both quite shy, but last night I sat and watched them for awhile. They both act...odd. They lie on the bottom of the bin, on their sides and look dead...but they aren't. Oftentimes they'll lie on top of each other, like their cuddling. They also seems to be nibbling on each other, but neither seems to have parasites. I'll try and get some pictures and maybe a video up, I can't really explain it but it worries me.
Laying on the bottom and laying on their sides is bad news. It sounds like swim bladder problems as well as digestion problems. Pictures would be great, but could you also tell us what their poop looks like? Is it white and stringy?
Not really on their sides per say, more like just on top of each other. It doesn't strike me as swim bladder, but I've only ever dealt with sick bettas. Poop is a light brown, similar in color to the pellets they eat.
Sitting on top of each other is not something I'm familiar with at all. Maybe you could PM Lupin. He is the supreme goldfish authority around here. He might take a bit to get back to you, but in the meantime just keep a close eye on them.
