Yes they can become deformed prone to disease.if left to ther own devices .
If dune by selective breeding you can go on and on for many generations or years.
This can only be dune by starting with good fish only breed with the best. any Fish are that are deformed or fish that don’t swim properly or dont look normal you must remove them. I am not saying this is the best way to breed fish. but it is for me as most of my fish are very rare and can be very difficult to find new stock.


The most common coarse of deformities and diseases are from. pore water quality. Incorrect feeding .or temperature .

I must agree with Fish48. Although there is a lot said about the poor results of inbreeding, inbreeding is the fastest way known to establish any desired quality in a fish. The down side is that culling must be done regularly without exception. The good genes are reinforced just as often as the bad. If you cull the bad wherever they show up, the line will quickly improve. If you are silly enough to breed deformed fish because you think they are cute or somehow think they deserve a life of their own, you had better stick to out-breeding and accept run of the mill fish. It is all you will ever see from your breeding efforts.

it isnt growin ether all the others are alot bigger than it could its growth be stunted the other molly bullies it a little but i dont think it would be enough to stunt it

If your fish is being bullied and made to act subordinate, it may not be getting enough to eat for good growth. I find that all of my mollies from the same drop stay very close to the same size for the first several months. After they mature, some grow faster than others and the faster growing ones are almost always the more aggressive ones.
