Porites Pest

[TimothyJ]

I noticed a few spots (white) on my porites tonight and was curious if anyone may know what it is?

It's still tough to make out much detail. You should get a magnifying glass and bave a closer look. Do these white spots look what's in this pic? If so, Montipora eating nudibranch is what we call them around here. If not, what can you describe about them?

they do look a little like tiny nudis...

These are Phestilla minor and they feed on porites exclusively

Any known way to eradicate these?

I am not aware of any natural predator if that's what you mean but Phestilla minor eats porites exclusively so unless you have lots of porites they are probably all on that tiny frag. I would just manually remove the Phestilla minor and look for any remaining eggs (which should also be on the porites).
