Who Gives A Fish Forums

hey all, just wanted to check in about my 2 percula clowns. they seem to be breathing pretty heavily, mouths opening and closing a lot.

i've been testing my water parameters and everything looks good, they're eating normally and swimming fine. is this something to worry about or is it just normal behavior for them?

It seems like a fairly normal behavior, but I'd keep an eye on how fast they're breathing. If it's rapid, it could be a sign of stress or illness. However, if they're still swimming around with plenty of energy and eating normally, it's likely not a major concern. Just as long as your water parameters are in check, particularly with ammonia and nitrites, I think you're probably in the clear.
