I took them the same day I posted, males about 3 to 4 inch, females 2 to 3Beautiful looking specimens. What size were they when you took the photos?
If he is head shaking and flaring his fins and he hasn't killed her yet they will more then likely pair up, just be patience.I'm hopeing that my 2 festea pair up, they follow each other around and the male quivers every time he gets close to her. So i guess I'll have to be patient and wait.
If they do breed I would be worried about the plecos around the eggs
