I have a baby golden albino, very young, doesn't even have their back legs but I'm determined to keep them alive. They've been having floating problems for a while, an obvious bubble in them. I don't know what to do. I've tried water changes, I've tried fridging (many people recommended), I've tried just leaving them be to see if they'll burp it out but the bubble is not gone. What do I do? I feel real bad and I've been really excited about this guy. If you need photos I'll attach but it's just a baby with a bubble in it's neck.
