RE: Mandarin Pairs?
My understanding is that they may keep to themselves until the feel the urge to mate. I am not sure though. I have seen video on reef central I think of two mandarins hanging out together (presumably male and female). I expect they tolerate each other, and that may be what you get.
When it's time to mate they dance to each other, then swim up into the water column and release the goodies. <-- technical term.
"Maybe in order to understand mankind, we have to look at the word itself: "Mankind". Basically, it's made up of two separate words - "mank" and "ind". What do these words mean ? It's a mystery, and that's why so is mankind." ~ Jack Handey
