Just wondering if a pair that are siblings can produce a beautiful fish? On that topic can two not so attractive siblings produce some stunners that look way better then the parents??

If any one has some stunning inbreads I would love to see!

Thanks
 
Yes, they can produce good looking offspring. I'd venture to guess that a majority of fish being sold in the hobby are offspring from siblings. Most folks that I know start off with a group of fry and let them pair off to breed.
 
Inbreeding can cause more variability in appearance, so a lot of times you can get some stunners and also get ugly drab fish. But if you keep inbreeding, like breeding brother and sister and breeding there offspring together and breeding there offspring together and so on can make some weaker or deformed, so its good to add unrelated fosh into the line.

sorry for the extra info, sometimes I get carried away lol.

It's important to add fresh genes to a breeding pool , but this is easier said than done. Sourcing fishes from different sources and pairing em up will take a lot of patience and tanks ;)

I would imagine it takes a while to get terrible genetic deformities from inbreeding, unless you were constantly raising and breeding siblings to siblings or siblings to parents. I've paired up F1 and F2 siblings and gotten amazing fry -- healthy, even growth rate with very few defects and culls. Ideally people would eventually find a separate source and mix with these fry for future breeding to keep the bloodlines varied.
 
Takes many generations to cause noticeable defects, look at jack dempseys, hardly ever see wc, and with the amount of morphs out there, inbreeding especially to get ebjds must be hundreds of generations. Yet, I still have a healthy, Undeformed ebjd.

This is correct
and if a genetic deformity shows up in a new generation you can always go back a generation or two. That's how Line breeding works.
