Hi guys, I think I have a Zoa eating nudibranch. Don't really want to dipp over 50 frags in revive. Does anyone have experience spotting these guys?
 
They usually blend right in with whatever they are eating... You may have to bite the bullet and dip the frags.
 
They glow green under blue/actinic lights,but even if you find and remove one there will be egg clusters which will hatch in a week.
 
Shine a flashblight at night or very early in the morning before your lights come on, thats what I did

I've found them from tiny spec size (recently hatched???) to 3/4" long. You're probably going to have to dip... I've used flatworm exit successfully to rid a colony of them. Just a few drops in a tupperware. For me, many of the colonies that were getting munched, partially closed for weeks, have opened up within 15 minutes after killing the predator...
 
They look like the zoa they're eating. Baster works. Or the box trap lol J/K

Can you add a fish to the system? Cosmetus and a few others are great hunters :) Otherwise, deff hunt at night for them. They fluoresce the same as what they're eating, so look for a moving "polyp".
