Hi everyone, I have a 2" TSN its very healthy and eats bloodworms like a monster, it has this small little balloon stomach and looks really nice. The only thing is that TSN's has two fins on either sides but my TSN has two fins on the left side but only one at the right side, it misses the one behind the first one. Should I be worried? If it was bigger I'd think that another fish ate the fin but its so small and I don't think it has been with other fish bigger than himself yet. Could it been born this way? cause I noticed this a few days ago and no sign of growing it back yet
thx for any help
