I’m just saying that if you take two Regal Angelfish from the Red Sea, there is a 100% probability that they are going to be yellow bellied. And if those two angelfish mate, the offspring have a 100% probability of being yellow bellied. Any variations from this scientific fact is just BS. Thank you.
As I said - you should give it a try.
In your case about all I can possibly agree on is that you want a Regal from a certain place. And when you purchase it, for X price, that is what you expect. Makes sense and I see nothing wrong with that (not that you are asking for justification).
Personally speaking it doesn't matter to me and I'd grab a captive raised any day. But that is just me.
