Male or Female?

Hello!

I have just adopted this handsome fellow:



And am concerned he may actually be a pretty lady. Petsmart said that he's a male halfmoon, but it doesn't seem like his fins are quite the right shape for that. So, I submit him/her to you experts. What do you think?

Congratulations, it's a boy!

He's not a halfmoon, he's somewhere in between a delta and a veiltail. I would call him a roundtail.
Very nice coloring!

Looks like a boy to me :)
