So i have had my new clown for about 3 days now , he is the only fish in my tank but plan on getting him a mate . Over the last few days he has made his home the back two corners of the tan, one being under the heater and the other under the power head . He doesnt seem to stray to far away from these locations just hangs out there . He is eating fine , twice a day and water is fine ..... Am i just being paranoid or is this normal behavior???
