Need Help Sexing This Betta

[FishGuest5123]

Good evening! Can someone look at my pics of this betta and tell me what sex you think it is? I bought it as a baby girl when she was very tiny. She’s been raised in my sorority tank and doing fine. I just can’t locate an egg spot on her and her fins are long. Any experts out there that can tell by body shape or anything else besides egg spot? It’s hard to get her standing still. Thanks so much.

How old is the fish?

Going by the fins I would say its a young male.

If you look at the area where the fish poops from, the females have a small white ovipositor (egg laying tube, where the poop comes out of) and the males have a dark ovipositor.

Yes, I can see them on the rest of the girls but I never can a good look at this one because the fins are longer. I guess I’m going to have to net it to get a good look. I just don’t need a male in with a bunch of females! Right now it’s only about 3.5 to 4 months old. It has gotten very territorial with a tiki head house and won’t share it. May be time for one more tank! Thanks so much!

4 months old with fins like that would be a male.

Most definitely a male. So yes. You will need a new tank. [emoji16]

I was leaning the same way but I finally caught it in a net and it has a white egg spot. Now I don’t know what to think! Could a young male have an egg spot?

females have a white ovipositor, males have a dark one.

 

[FishGuest5123]

OK. Here’s some pics of her underside.

I can't see the ovipositor.

The ovipositor is a tiny little tube about 1mm long and is where the poop comes out. The next time the fish goes to the toilet see if there is a small white lump there.

Young males often have a false egg spot and those normally go away as they mature. If you stuff the belly with food it may reappear though. A female always has a noticeable egg spot and I do not see one on yours. Plus the fins are far too long for the average female CT. Couple that with the body shape (big head, not terribly fat like a female CT) it is likely a male.

Look at the ventral fins on the fish they should tell you everything you need to know.

The egg spot in Nick's images is the ovipositor (egg laying tube).

I know what the ovipositor looks like. That’s the problem. Lol. There isn’t one. Today, I have a bubble nest in my sorority. Where can I put another 5G???

 

[FishGuest5123]

At what age do they start breeding? I’m asking because I’m getting a new 45G tank for Christmas. Then I’ll have a empty 10G and stand that I can use. He’s probably about 6 months old if I’ve had him almost 4 and he was 2 mos. when I got him. He was very, very, tiny. That’s why I took her now him.

Wait, I just found a pic of her when I got her in August. So she/he is about 5 months old.
