Angel fish fin droop

I noticed about a week ago that my one angel fish's dorsal fin is drooping backwards right at the top. I dont remember this fishing being like this when I first got it. It seems very healthy, active and eats alot as do all my fish. Any one have an idea of why this is or is it just maybe a deformity?

Thank you.

 

Dorsal fin at the top right? One of my previous Angel's had it too. This one was in a very small and shallow tank (sorry didn't know better) and I think this might have been the case? What size is your tank?

I have heard that if an Angel is held in a too dense tank (like too much angels per liter) their fins won't form perfectly. Only my speculation on my experiences. More help from the expert, @Dirk Bellstedt maybe?

 

Its 91cm long and 38cm high. I have only 2 angels in it with a few corys, 2 ID sharks(yes I was ignorant and didnt know what I bought), a gourami , a black labeo and a plec. The plec and ID's are still small as is the black shark at this stage.

 

Well that's the same is my tank and I have two with perfect fins. Sorry I'm all out.

 

Charlie, could you get a picture of it? It would definitely help us.

 

Here is a pic.

and of the whole tank to get a size perspective.

 

Doesn't look too bad to me. Some angels develop strange fins. The main thing to me, is that the fins are all extended out, and not clamped. Clamped fins are a sign of distress. That fish looks quite happy and healthy. If it has a healthy appetite, then don't worry too much about it.

 

@Sean J. Thanks alot. Ya he is very happy from what I can tell and eats plenty too.

 

That's exactly what mine had.

 

Pretty common genetic anomaly associated with Angels - comes from years and years of inbreeding....nothing to worry about at all.

 

Thanks all. At least I dont have to worry about it being something I may be doing wrong now.

 

Hi CharlieB,

Azure is quite correct that this is genetic. It can be eliminated by careful selection of breeding stock to have perfect fins, but angel breeders in South Africa are all too often only interested in quantity and not quality, a great pity indeed. In my fishes, I insist on perfect fins, also with regard to fin and tails extensions. To illustrate what I mean I have posted pics below of an adult wild type male which perfect tail and ventral (bottom) fin extensions. That is what the fins of an angels SHOULD look like, in opinion.

Kind regards,

Dirk
