Noodies!

I have some supposed zoa-eating nudibranchs.. What to do? Some of my Zoas are attached to LR so taking them out and dipping them repeatedly isn't really an option. Is there anything else I can do? I manually removed all I can see but I know there are prolly 3 for every one I can find..

they are in a Red Sea testing kit lid for size referance.

Manual hand removal is going to be difficult. Hunt with a blue light at night. They change color depending on the polyps their eating. They are easy to spot when polyps are closed. Also remove eggs off the side of polyps. Also might want to try a wrasse.
Personally I would remove the rocks and put into qt for regular dips...

Flatworm Exit

Jade wrasse And a yellow coris - Halichoerus chrysus will eat them up.

It's a 180 with Zoas growing on multiple large rocks in the middle of the aquascape. Will flatworm exit kill the eggs or just adults?

 

[Fragzilla]

Just the adults. Do it every 5 days for a couple of weeks. 1-2 drops per Gallon of tank water.

You can also make a super strength dip from the FW exit and dip them for a couple hours in the solution.

I've done it several times at 4 X the recommended dose in my Zoa tank with yellow tang and apart from the odd bristle worm and starfish floating around you wouldn't know anything was going on.
