I have a lone glass catfish in a 10 gallon tank with a couple of guppies. A few days ago he started to swim vertically (straight up and down). Today it is swimming wildly. Its spinning and zipping through the tank. It makes me dizzy just looking at the poor guy. I assumed he was stressed out so I did a 20% water change. He's still acting crazy. The guy at the store I bought him at said they had no problems living alone but now I'm reading that they need to be in groups. Could this loneliness be making him crazy? Or could it be a disease? HELP!
