I just got a fry that was marked as a male. However, from what I've read, it's not easy to sex them at his age, so I'm taking that with a grain of salt! However, I was wondering if anyone has a general idea of this little guy's sex or breed. I'm guessing crown tail but I have no clue! Also, any guess on the color he'll be? The black rings around the eyes are interesting, do they give any indication?

I would say that is a baby boy. Ad far as breed, his is a Betta splenden. Also, rays grow faster than the webbing, so I wouldn't say CT just yet. His dorsal and anal fin don't appear to have any web reduction.
I have no idea how to guess the color, but I would say his eyes are just his eye color.

He's growing! Here's how he looks now. Do the splits in his tail mean anything?

definitely boy. and those are his rays. they split naturally like that. Normally petco babies are veiltails but I have seen some crown tails and double tails. Wait until his tail grows some more you can tell a lot by how many rays they have. Veiltails can't have more than 2 rays.

Thanks! So just to make sure I'm understanding, the rays are the split in the end of the tail? I'll keep posting his progress here as he grows

The rays are the ribs or battens that stiffen the fins. They are counted at the edge of the fin. His look like 2-ray branching, which usually indicates a veiltail. There are 2-ray Plakats, but he's not one.

As for color, he'll surprise you.
