There is a similar deformity in clowns. ORA sells them as "stubbies". Kinda cute imo. Shorten lifespan and frequently sterile from what i understand though.
Ive heard of em!
They (short bodies) only come from captive breed operations due to well, survival of the fittest. Most of the fish in the SW trade are wild caught. And those of course are generally fit specimens.
Now that were seeing a huge increase in captive breeding for SW fish Im sure more will come to market.
My short body red tail was imported from a thai fish farm.
No surprise clowns are the first SB's considering we CB all kinds of color morphs.
Id spend a stupid amount of money on a SB black storm clown!
