What... I must ask?
They've been around for ages as "painted" glassfish and such, also "jellybean/bubblegum" freshwater parrotfish? The only difference now is they are putting spots and such on them. It was bound to come to this. What about wacked out hybrids like balloon mollies and bubble eye goldfish, and even whatever (open to argument) cichlid cross resulted in the freshwater parrotfish to begin with?
It was always crazy, and it is just logical that they would try designs. But it is nothing new..nothing new like dyed corals and anemones too.
