Dinos?

I don’t have a microscope yet, but does this look like Dinos? My goniopora won’t come out now that it’s covered in the stuff.

Looks like it. Spent too much money on corals to lose them to dinos so I bought a microscope to ID them. Only way to combat dinos is to properly ID them

Goniopora like good flow, higher nutrients, and probably placed on a rock Rubble in the sand bed.

Try that and see what happens. They don't have to be the 6 month coral of death.
