My pair of Genicanthus Semifasciatus
 

I love the Genicanthus genus because males and females display different colors and patterns. With all the species in this genus, I like G. Semifasciatus (masked swallow tail) the most because males and females look like two species.
I have a female and male G. Semifasciatus for almost 2 years now. When I first bought them, the male was still in transition phase (not much yellow, little vertical bars). 2 years later, the male has completed the transition and becomes a beautiful fish. Better yet, in the last few months, I notice the male and female are engaging in courting rituals.
First some pictures of the fish:

And last but not least, a short clip of their mating dance.

Beautiful! They look big too! I love the Genicanthus genus as well.
