Lyretail Anthias - what are they doing?

[DmitryB]

I got 2 Lyretail Anthias (Anthi-eye?) from a fellow reefer here at R2R. Beautiful, very active fish. One is larger than the other. The smaller one is the deeper red color, the bigger one is kind of lavender pink. This morning was my first time seeing them at "Dawn" - and the larger one is doing these head-dives at the smaller one. What are they doing? And I assumed the deeper red one - though smaller - was the male... (It's very blue because this is the very beginning of the light cycle, the blue/uv lights are on at 2%, so you can't see their colors now. But the one doing the diving is the lighter colored one, coming after the deeper red.)

I can't help with the behavioral question, but yes, "anthias" is both plural and singular. One anthias, two anthias, etc.

I have 3 since the beginning of the year, one male and two females. The male is often randomly aggressive to the females but no marks or fin damage.
