Male

[xXGalaxyXx]

From the ventrals, I would say male. An egg spot isn't a sure-fire way to tell gender, even on the older fish - one of my males who's a little over a year old has an egg spot and yet has fathered a spawn.

Also, I would never, ever put two betta's together if you're not sure of the gender, and sometimes not even then. You're lucky your crowntail is passive - he could have easily hurt your white one even if it is a girl (almost lost a female this way once - was trying to breed her with a male and he just ripped her up. Can't even imagine what would have happened if she was a male! x.x) You even have to be wary about having a small amount of females together - one girl will be more dominant than the other and will pick on her.
Anyways, just a little side track. Not trying to be mean, I'm just saying that that's probably not the best idea, even if your crowntail didn't do anything to the other fish.

Bubble nests are never a good way to tell gender. Some girls blow them too, and some males never blow them. The only sure fire ways is to get him/her to flare and to check their ventrals.

When flaring, males will tend to flare sideways and turn their head in order to look bigger. Females tend to flare head on and face the mirror. The length of the ventrals suggests that he is a male

I say male. Males can have egg spots too. He looks like a male- in fins and body. Females have a shorter body than most males. Males are longer usually. And it's more likely to have a male with shorter than normal fins than a female with longer than normal fins. One of my friends has a female with long fins, but no where near as long as your's.
