A. Elizabethae sex??

[C.Elizabethae]

is it two males? I read a ton of these same posts on here and 24 hours later they find eggs or the female finally colors up. How about their behavior? The larger definate male seems to be increasingly interested in forcing the smaller one out of that pogostemon it has retreated to.

I can’t see enough of anything in that video to make a judgment. Sorry

My go to for sexing these is the caudal (tail fin). In general, males will only show “pattern” on the bottom half of the tail. Females will display that banded pattern on the entire caudal fin top to bottom

Looks like a male and a female.

However, the aquarium you have them in isn't suitable for them, Apistogramma are sandsifting fish and require a fine substrate with leaf litter, as well as plenty of caves and sightblocks.

I am waiting for a pair that I have ordered to arrive. Looking forward to trying to get them settled and happy

The one on the left at 0:41 seems female, and the right is certainly male. Based on their size, I think you've got a good shot at a pair.
