I have a pair Od OScellarus that spawn regularly for me, every 15 days, I am raising some of their fry. The female is always dominant over the male, just being clownfish. I have a second younger pair that are very active and the female is dominant over the male. These are getting ready to spawn from what I can see, cleaning of a spawning site, tail dancing etc etc. As far as color my CF get mysis, cyclops eze, ocational brine shrimp, and ocassional flake. They are very dark in color almost a mocha color. Sounds like yours should be spawning soon, types of food has a lot to do with their color and how comfortable they are in the tank.
