Bolivian sexing help

[FishyBusiness]

I just got these 2 today and I believe I have one male and one female. I know it's the coloring in looking at because they're so little. I don't know if 2 males would fight as they matured? The one with more color and darker stripe thru eye has pink on tips of fins, hard to tell in the pic, sorry.

Hard to tell, but if I had to make a guess, I'd say the one on the left is a male and the one on the right is a female. Not sure though.

Bolivians are best sexed by venting since there isn't much for dimorphism between them.

Yeah I was looking and it's either 2 females or 1 m, 1 f
