I put four blue damselfish into my tank about three weeks ago. Within a week small divits in the sand began to appear. The look like some types of nests that I have seen freshwater fish make. Are they mating or is this just natural behavior? (The tank is relativley new and they are the only inhabitants.)

Normal behavior. My maroon clownfish (which are damsels) does this also. At least until I went bare bottom.

Thanks, I was worried that I was going to have a bunch of baby blue devils swimming around.
