I just bought a female betta from petsmart that said its a halfmoon betta. Ive had a halfmoon female before and this isnt what it looked like, shes too long and skinny and also shes she flares up all the way her tailfin doesnt make a "D" shape at 180° like its supposed to, this is a young fish so make when she gets bigger it does but im not too sure, can anyone tell what kind of betta this is?
