So I currently have both a young Tig and a young Lima in my tank. They both continue to insist on swimming up the glass. They're generally stationary but are obviously maintaining their position against the glass. The tank is about 36'' high and they're maintaining a position about 6'' - 8'' off the floor of the tank.
I've heard a lot of theories on why they're doing this. Could anyone offer their advice as to what the issue is?
