Nudibranch on my zoas?

[jordanphulet]

All my zoas closed up then I saw this, any clues?

Pluck it out of there and get a few good shots of it. It may be an Aeolid nudi, which is a predatory species, but we'd need a better pic to ID it properly.

i had that same exact critter eating my zoos.
once started, they began to chow down fast and eat 20 true blue zoos in a couple days.
I had to take all my zoos and place them in the front of the tank and looked at them 2x per day to seea ny nudies and then pluck them off

BUt today my tank is nudi free

fresh water dip them immediately and keep you eyes out for any others. also using a syringe that comes with a salifert test kit to suck them out works well.
