How to tell a bettas age
Hello everyone! I was just wondering if there are any ways to tell how old a betta is. PetSmart employees donít know how old the fish are when they get them in and I have quite a few males from there Iíd like to know the age of. Iíve googled how to tell/estimate age multiple times but donít ever really get a clear/straightforward answer. Any and all help/advice will be greatly appreciated! Thanks in advance!
