SPS bleaching. Could it be fish related?

[Diogenes]

So I came home today to what it looks like 2 dead corals. They were knocked down and bleached. I still need to run tests to see what's going on, but I noticed something interesting. A Jewel Damsel I got 2 days ago won't leave those 2 corals alone. It keeps pecking at it non-stop even after knocking it over again and again. Now, I don't know if it's simply just eating some dead tissues, or if it's possible that it pecked at it until it got stressed enough to bleach it. Has anyone ever experienced anything similar?

any more sps in the tank?

1 more on the other side of the tank. Away from where the damsel has been staying. That one is ok so far

Not fish related.

Could be dead and bleached because they fell in the sand. Damsel could be trying to eat some sort of flatworm. Could be a lot of things. Damsels don't typically murder coral indiscriminately

I know its an old post but it has my interest. . It may sound odd but damsels clean an area usually a smooth surface to prepare a nesting surface for eggs. By any chance is that what it was doing?
