I just picked up a pair of Agassiziii’s. At the store it looked like they were a pair since they would move all around the tank together and we’re interested it what each other were doing. Once I got them home and in a tank their behavior changed. They don’t really pay much attention to each other and just do their own thing. I also noticed on the one I thought was a male the dorsal fin is pointed at the end like to other. I have attached photos of the suspected male.
