Yes, the boys chase the girls, and there have been lots of pseudo-spawnings, which are pretty frenetic affairs. Sorta like high school.Question for you @sir_keith, if you have moved them all in together, do they show any fun traits as a group? My single specimen isn't very social with the various catfish in the tank, he just kind of hangs around.
Strange; mine are active, but certainly not frenetic, often just chilling out on the substrate. Perhaps it comes with maturity...I set up an aquarium for a client in NY with ~12 true SAE. They couldn't handle the frenetic movements and had me remove all but a few.
