clown dance

[lriddell]

I have just noticed that my nemos are doing a quick tale movement at the base of the sand bed under some live rock. i think the male is the one doing the motion. quick tale wiggle.
What is this? What if anything should I be looking for?

Its possible that he is fanning eggs or mine just like to move sand around with there tails, like they are making a burrow

Very common for the clownfish to "clean" the area around their host. They'll move shells, corals and sand that they are not happy with
