I've seen an albino bass for sale over here once, not sure if it was a peacock or lmb, but it wasnt that much more then its regular counterpart from what i remember...
Never seen or heard of one but I'm guessing it won't be long before the scientists in the east develope some.We already have quite a few hybrids in the hobby and just yesterday I found myself standing in front of a tank full of short bodied peacock bass!
