Molly Breeding

[Juliensiss]

I have a question.

Mom and Dad molly have lots of fry 5 make it to adolescence the first few months then 8 more survive. Can or do siblings mate? What will be the outcome? Over crowding is becoming an issue and if they can breed I am in trouble!

Yeah they can breed. What size tank? If they breed, the babies may come out deformed.

My tank is 30 gallons. All of the 10-12 fry look the same so I assume they are from the same parents.

Will they survive and what kind of deformities will they have?

Tehy will no doubt survive. But they could have wierd fin angle's, stunted, extremely long, skinny, fat, bad vision and the like. Maybe not after the first time but if they keep breeding with their own strain, then it is likely to happen.
