HI does any one know why an angel fish would turn flips and shake violently in the aquarium?He weas acting strange ,so I did a 1/4 water change and he is still "crazy",he has no marks or outward signs of sisease,and all the other fish are fine.is he just nutts?

doesn't sound too good - sounds like a case of angel epilepsy. But take a very close look at its skin to see if there's any bugs or things attached to it (esp under the fins). But it really doens't sound too good for the angel. good luck

What you are discribing seems to be what ive seen at LFS when they put a new fish into a new tank without acclimating them. They go kinda nuts and do flips, So maybe somthing is outa whack in your PH.

What kind of angel?
What size of tank?
Other inhabitants?
Tank parameters?
How long have you had the angel in this tank?

Need more info. Right now it could be anything.

Is it a new fish? If so, it may be a gill fluke. Try a fresh water dip for a couple min or so.
