Hard to tell with bolivians, ive actually been reading up these myself, and id think the picture with the one sideways is a female and the other is a male. but they say the only sure way to tell is venting them
I'd say in my limited knowledge that the one that we really only get a back view of is a male. Only because of the extended dorsal fin tips. But from what I've read also te females top and lower fin will not extend past where the tail ends and the fin begins. I just picked up 4 Bolivian rams over te weekend so I've been trying to figure this same thing out
