I have a pair of masked swallow tail angelfish (Genicanthus semifasciatus). They spawn every few days. Bellow is a video of them doing the mating dance.
Male genicanthus is on the aggressive side in general. Watch them closely when you introduce them. Provide a lot of hiding place for the female. I personally have a few genicanthus pairs and know their bonding process can be violent. I am used to that. But if you are new, you may be very nervous. I would let them sort out if it was my pair. That's what they do in the wild anyway.
Here's my pair. Video taken on the second day that pair been in the tank. Just taking the video to show that the fish are eating pretty aggressively.
The male is a little toward the aggressive side. But it keeps my purple tang in check. They only been in the tank for a week now but I like them more and more. I never thought much of the swallow tail angels.
LamboBoy- that's a beautiful pair you have! Best of luck with them.
I have a male/female pair of g. caudovittatus and two female g. semifasciatus. There is not a lot of aggression, but there is a hierarchy. I'm hoping one of my female semifasciatus turns male some day.
Two females are getting along. Is one more aggressive than the other. Any chasing?
