As a general rule of thumb to newer breeders if a batch of fry have a large
percentage of a consistent deformity/mutation then there is a higher degree
of likelihood that water quality or other environmental factor is likely to
be responsible and therefore is not genetic and therefore could be bred
with if necessary. If you correct the percieved problem and the deformity
persists but in small numbers then there may be a genetic fault to be
considered also.

I also realise that our resident "Devil's Advocate/Agent Provocateur" will
not necessarily agree but it is worth using as a starting point .

<<So true Andrew, I've done this myself. Not long ago all the fry I
raised had deformed fins. I corrected my water problems and know these
fish are still good for breeding. I've kept a few because I have no
other stock. I'm not too embarrassed having these fish around and
explain to folks visiting my fish room what happened. Still I'll be
glad when I get a new generation out of to replace these poor finned
fish.
But if you're not sure of the fishes history you need to be a little
more circumspect. It takes a fair amount of time and effort to confirm
its was just the raising conditions that produced poor stock without
this history. If I've no other choice I might do this, but if I can
get better stock I'd definitely would.
