My original male clown died so I have had this new one for a few months now and I think they have paired up, itís just odd that the female is shaking and picking at the heater.
The shaking behavior can be for a number of reasons including mating behavior, or even irritation from a parasite. It could even be a simple as just a habitual behavior she's picked up. As far as har picking at the heater, there may be a slime coating of protozoa that she is eating or even feeding to the anemone if you have one. If you do have an anemone, and most of her shaking is done in and around it, she may be stimulating it to feed.
