Does anybody know if it’s bad to breed the parents with their offspring?
I thought it was ok for fish. At least, for a few generations.Another thought I had. I’m not just going to keep just any of the offspring, I’m going to keep some of the prettier ones for future breeding. That makes sense, right? Afterall, most people that buy the fish probably won’t buy them to breed them.
i heard if you breed offspring together they are weaker so i would assume its the same with parent/offsring breeding which is why i would leave the fry in my planted tank as they would probably get dissposed of quite quickly
i know where your coming from in terms of selecting fry for future breeding but from pictures that ive seen of young fry you would have to wait t least 10 weeks to be able to see the colouring on them and i would think longer to sex them

Generally, with most aquarium-type fish, a couple generations of linebreeding/inbreeding doesn’t seem to greatly weaken the strain, so I’d personally feel comfortable with doing a F1 or F2 with my current stock before really needing to bring in new genetics. It’s the accumulation of multiple copies of weak genes that really causes problems. Unless the parent fish are really faulty to begin with, genetically, I don’t see the harm in a limited gene pool for the very short term.
