So I've had one percula and have been trying to get a mate for it. So I bought one online because none of my LFS carry true percula a anymore. So after quarantining the new fish I put them together. At first the new one started vibrating or shaking toward my original. Then they were latching on to one another's fins and locking mouths and spinning in circles around one another. They are about the same size, which I wish they weren't to make it easier. After about 15 mins the new one has stopped fighting while the original percula just swims near him and every now and then chases after him. Through the fighting I didn't see any new damage to find or body. Is this normal or should I be concerned? Any advice would be appreciated.
