Nudibranch

[Scoobers]

I remove this guy off the glass of my aquarium tonight and I am wondering if anyone can tell me more about it. It is pure white and maybe 1/16th inch long. I am not putting him back because of the risk to my corals. If anyone has any info on this guy I would appreciate it.

It's a predator of Montipora. Check all of your montis, especially on the undersides. If there's one of these there will almost definitely be more. You also need to check for their egg masses, which look like tiny spirals on the coral.
