Bicolor angle pair??

[Saltydrip]

Is it ok to house a pair of bicolor angles in a 55gal reef tank?? I read that they will pair up. Is there a way to sex them visually? My LFS gets them in all the time. Usually pretty small. My refugium is empy because it's new but it has some rock. If I could only buy one at a time I could keep one in there untill I find the right sex partner. I have 3 good LFS in the area that I can bounce around to so it should be an easy mission. Actually I read that If there are 2 females one will turn male. Is that true?? That mightmake it easyer!

The tank is healthy with overkill filtration. I'm set up for well over 100g.
Curent stock list
1 pixy hawk
1 false percula
1 scooter blenny
1 lawnmower blenny
1 coral banded shrimp
About 15 assorted snails. In refugium and tank
Many corals to come now that I'm getting good with water testing and chemistry.

I think your tank might be a little small for very active fish like dwarf angels. Bicolor angels are one of the biggest Centropyge species (around 6"-7" full grown). If you have your heart set on a pair (and the budget/room), why not set up a second, larger system just for them?

As far as sexing/pairing them goes, I'm not sure. From glancing at a few articles online it looks like they're protogynous hermaphrodites.
