I got my new 10 gallon aquarium a couple days ago and everything seemed to be fine. But tonight my albino catfish Albert started doing laps around the surface of the tank. I’ve tried to do research but I’m confused with everything sites are telling me. I have a tetra whisper 10 filter. It started doing the laps right after I turned off the lights. The other fish settled down but the swimming was disturbing them I guess because they started swimming around again too. If anyone needs a video I can try and post it but he’s literally doing circles around the entire tank. Can anyone help me?
