Blue acara additions?

BAs can be tricky to sex from a glance, best way is definitely to vent them. Or try to get cloes up pics of vent when they do their "breeding" dance.
The males do tend to be larger and have more of a bulky forehead, and the guy in the back fits that description more than the fish in the forefront, but it could possibly be a subdominant male who hasn't developed those traits. Trailer on fin of smaller one would make me think it's two males. But again, without a good vent pic it's just a guess.

Well I’ve been closely watching them since I last posted. The smaller one looks like a male but they are shimmying around each other, cleaning and defending a rock and digging pits but no breeding tubes dropped. They do this every few weeks but never any eggs. Maybe the smaller one is pretending to be a female so it doesn’t get beaten up?
Possibly these particular fish swing both ways?

Same-sex female pairs are common but I do have two male Heros who go into spawning colors and defend sites together (and beat up all their tankmates).
