Are you able to get any pictures of flaring? With the ventral fins easier to see and with the gills fanned out to look for a 'beard'? From what I can see, it looks like maybe the ventral fins are a bit long and I don't see evidence of an egg spot so my really inexperienced opinion is possibly a male? I'm sure someone will come along with a better idea!

I may very well be wrong as well, but I am thinking this is a female betta, the abdomen looks slightly larger and rounded than it would on a male.

I'd say female at first glance, but as @Twist says we really need a picture of it flaring to be more sure

How old are they? Their body is pretty translucent and I can't clearly see ovaries, which leads me to think male, but they're pretty thick in the abdomen which is a more typically female shape so they might just not have developed far enough for ovaries to be visible yet. Very pretty either way!
