Is This Normal?

[becca320]

Hi ,
Was just wondering if anyone can tell me if this is normal or not??
I have a pair of Angels which have sucessfully spawned, I am still not sure which one is M/F but am not too concerned . Anyway I have noticed that gradually one of them in the first picture has a strange shaped top fin it kindo of arc's??? I would not want to let them carry on and breed if this is some kind of deformity, so have been searching others pic's to see if this is normal. To give you an idea on size he/ she is about 7 inches from top to bottom and the other one with normal fin is about and inch and a half smaller.
The babies all seem fine, cant get a pic as they are too small
Any help as always much appreciated.
Becks.

1. wirh strange fin

He might of just been kept in a small tank for part of his life (I believe the top one is a male) and hence the fin just naturally curved. How long have you had the angel? What size tank are they currently in?

If the curved fin is just from being in a small tank, then that is not a genetically passable trait so no need to worry about the little ones having a bent fin
