3 spawn and all females

[Aniket]

I had what was suppose to be a female betta. Egg spot and short tail. Grew into a beautiful male with a long tail and he lost the egg spot. Hard to tell with juvenile bettas. What type of betta is it? Tail type of parents?

Its VT and CT mix

I'd like to see pictures of the juveniles. All will appear female until they suddenly don't. Egg spots are not a good way to determine a young betta's gender. It's a combination of egg spots, fins, body shape, yellow ovaries, and a beard that really shows who is what. For female, looks for the yellow patch within the body, showing where the ovaries are. They will also look plump and have very prominent egg spots even at a young age.

Males will be more stream-line, have a hint of a beard, their heads are larger in comparison to their body and fins more extravagant. Young males can and often do have false egg spots. They become more prominent if they were just fed.

How old are they and how many in each spawn? Are they from the same parents? There have been studies that suggest the more spawns the parents have the fewer males produced. Can't find out where I read that, it was a while ago.

These are few pics

They are too young to be 100% sexable at this point. I would guess that the last 2 pics are male, based on the head shape and not-so-plump belly area. I assure you, once 1 juvenile starts showing that it is male the rest of the males follow shortly after.

All of them showing egg spot. Dont know if they are male

Egg spots are not a determining factor for sexing young bettas. I've got a spawn of ~20 juveniles growing out right now and I can see some males already. The males have an egg spot but I'm 90% sure they are indeed males.
