Ever had an azure damsel do this?

Ok, this little guy has been working like a madman to dig this hole and the clowns even helped him. He uses his tail like a fan at 800 RPM and blows the sand away to make the hole.

Why is he doing this? Is he getting ready to murder another fish with the clown help and bury him in the ditch? He really moves a lot of sand with his tail motor.

How many damsels are in the tank? possible nesting behavior. Any other changes in behavior?

Yes, my Azure is quite the excavator and manages to bury some low lying corals on occasion. He even moves some Zoa frags on the sanded if I place them too close to his construction site.

One other azure and a springerie

But why? They don't sleep in the sand. Why are the clowns helping him dig this pit?
