I'm not sure if those "betta bullets" are the result of cutting the back end off of fry... Could be 50/50 mutilation or mutation/stunting, I think. But I know that is how they get "heart" blood parrot cichlids. They cut the caudals off of regular young BP and as they grow (if they survive... Fatally rate would be high, I suppose), the dorsal and anal fins can grow overlap and or even fuse together over the wound.
When I was younger, we got some juvies from an uncle. He was really excited to give them to us, thinking they were some really rare special species (what the LFS told him). Must have paid a lot for them too, but he didn't know any better. We ended up getting two BPs which were normal and kept them together. Thinking back now, the five which had their tails removed never quite thrived in comparison to the normal pair. They also had other physical issues (trouble eating because of malformed mouths, swim bladder issues, etc.), most likely from poor breeding. We had them for a few short years, but I think they would have lived longer had they not been purposefully put at such a disadvantage.
Some people suck.
