Hogg Isles in the wild are rapidly becoming extinct. Hoggs, show very different colouration and size differences as compared to columbian BCI and central american BCI. Outcrossing does not do them any good, but dilute the lines. Similar to rosy boas. These animals are so inbred in the wild, that the bad traits have been mostly filtered out. It's up to us, to keep Hogg Isle bloodlines pure.
Now, don't get me wrong, I love hybrids, I have a few, but there are times when hybridizing or intergrading does more damage than good.
