My Angelfish are shaking their fins???

[Star_Rider]

mine(the males) do it when facing each other..I have two breeding pairs in a 55..it appears to be used to show threat.

it seems to be pretty common in tanks with several angels.

I've seen them do it when the water cools too.

I'm pretty sure 2 or more males in one tank will fight eachother
