Lmao I really thought for some reason I was going on this thread to hear about venting sex

 

[myster619]

Anyone?

Not sure, maybe male right female left... Side on view in tank is easier with centrals Imo.
Iirc With trimac females almost always have a black dorsal spot right?

Yes female trimacs almost always have a black patch on their dorsal fin, where males do not.

You can see from these guys the difference in the dorsal fin (top male, bottom female)

 

[myster619]

How big are yours?

Here are mine from side view. They both don't show the black spot, but the smaller one shows a little black in the dorsal when it is stressed.

Here is the larger one. 12cm followed by the smaller 10cm one

Here it is when stressed

Probably both male on pics. Very rare to get a female without.
