abnormal mouth on clowns

[adtravels]

I have noticed this on a few clowns in lfs of different species.
The abnormality appears as an overshot jaw. it is not too pronounced but gives the fish more rounded face

The fish ate well and were of a good size anyone else seen such abnormalities?

I would assume the clowns in question were captive raised. It is a fairly common malformation in captive raised clowns, though I'm not sure what it is due to.
