Yea that is what I thought already. Thanks for the help!!I wouldn't suggest any more than one generation of incest babies if it can be helped, maybe two if you want to push it. Any more than that and you'll have a lot of nymph deaths, and they'll be much weaker and more fragile than they should be if they were from separate lineages. Thankfully most species are pretty accessible, so it's not too hard to keep the gene pool clean!
Also keep in mind that most males have one less molt than the females, which is kind of a natural way to limit the amount of incest in the wild. It's still going to happen, but its a little more difficult since the females mature more slowly
