I got an otocinculs (sorry for butchering that my skills are computers not spelling) anyway I knew from past experience they die a lot when u first get them. Anyway he is bloated af and swimming upsidedown right now. I googled it saw it may a bacterial infection so I am pounding down melafix and pimafix. I'll change his bowl tomorrow. (Quarantine is a 2.5 gallon hexagon my mom kept goldfish in when I was 4). I hope you all can help.
