Accidental hybrids are okay, but designer fish often are the result of crossbreeding and breeding sibling fish over and over, which often results in a shortened lifespan. If it’s just a hybrid, that’s okay though.
If you actually believe designer fish are made by cross breeding siblings then you don’t understand that most ethical places keep track of where the fish come from and use different pairs to make new pairs of breeding fish. Plus many designer clowns are made from breeding two different types together.
Now that tang is beautiful and I wouldn’t mind having those available when I get to do my 300G tank!
