What is this guy???

[LisaD]

Found him trolling in my Whammin' Watermelons when I was getting a paly out of them. Some sort of nudibranch??
He's tiny so a baby... Also a very sticky "egg cluster" of some sort. Not real sure if I should put either find back in

It's a zoanthid eating nudibranch. Get all the eggs out, too; they will all hatch. Nudibrachs usually lay two clusters of eggs in circles, side by side.

Ok I got one more REALLY sticky egg cluster out. Hope I got them all. Is there anything I can dip the frag in that will kill the eggs?

+1 If you can add a wrasse that will eat them that's your best pest control if your tank allows for it.

ive heard of people dipping their colonies in bayer pesticide. I personally haven't used this method, so i dont know the exact amounts that would be acceptable to use.
keep an eye out for your colonies getting upset and not opening. at night when the colonies are closed theyre easier to see. They take on the color of the zoas theyve been eating.

CoralRX Pro works great for dipping. Not sure if it would work on the eggs though. Close inspection would be your best bet.

There's a new product out that's supposed to kill eggs - haven't seen any reviews on it yet, but, there's nothing that I know of that kills the eggs. Now that you're on the alert you'll be able to spot them.

CoralRX, RPS ALLout and Levimisole all work for preventive dips. My go to is CoralRx. RPS in my experience is pretty harsh on soft corals...not sure why, but stonys handle it much better.
