Female betas always tend to have really short tails. If the container that 당신 get the 물고기 in at the pet 샵 says "male" on it, and it has a really short tail, then 당신 should know what gender it is. Don't let the container fool ya!

So now 당신 know how to tell a male beta from a female beta. Enjoy your fish!
