Gill cover edges curled on Piranha
I have taken an old Red bellied Piranha as a rescue fish.He came with his 3 foot tank (which was in a disgusting state,owners never heard of a gravel vac?).
He is temporary homed alone in a 2 foot tank,while I clean out his old tank.
I have noticed that the edges of his gill covers are curled over at the edges,does anyone know what has caused this and if I can cure it.
My only thought is that is was due to the water conditions,dirty & very hard water (large ammounts of white build-up on the tank glass/filter/heater etc).
