Please help!
I dont know whether this is as a result of age? (2+ years) but one of my angels started 'floating' at the top of the tank, on its side last night. Swimming around on its side. will eat normally and periodically returns to swimming normally. It is large (body = 4.5 inches) - is it just getting old? I dont think it is swim bladder, but would appreciate any advise.
Tanks levels normal. Temp normal. No new fish added recently. All other angels are normal.
Changed from under gravel filter to bio wheel filter 2 weeks ago but no odd signs until now.
