Worth less. Most stores here you could probably even bargain it for free. I think the only deformities people would pay equal or more for is for compact or short body but un deformed. I hope i just made sense.
well he will never be sold so i guess it does not matter i was just wondering what would happen if his offspring gave off the deformity what the consequences would be. but none of the surviving first spawn have it so im good on that note
IMO I wouldn't breed it, or at least grow some fry out and make sure the deformity isn't passed on. Sometimes fish are born this way with misshapen bodies. I have had angelfish and severums born with what appear to be huge chunks out of their anal and dorsal fins. It's something most breeders would cull for.
