Yea angels are definitely not what their name implies hahaYeah I've had allot of trial and error when I first started out. Lol still have a hard time keeping angels happy and healthy, mainly just due to their aggression/fragility. Had to get my puffers some blood worms today just to get em to stop nipping my angels fins. How 3 pea puffers, in a planted 55g, destroyed an entire colony of snails, numbering into the thousands, idk but I do know they started nipping fins shortly after the snails vanished.
