Zoanthid eating nudibranches

basssnake · 06/27/2010, 02:06 PM

I have finally figured out why my zoanthids have been not opening all the time lately. Some will open and some won't. I discovered some very small brownish nudibranches crawling on them(they look like like worms with several antenaes and bunches of antenae looking things all down the back to the tail. I looked at some pics and pretty sure they are zoanthid eating ones.

Is there anything i can buy to help erradicate the problem? I read something about maybe: sixline wrasse, yellow coris wrasse, or a green coris wrasse.

Dipping isn't going to be feasible. I would have to remove almost every piece of live rock in the tank since my zoanthids have spread throughout the tank. In fact, I have about 500+ zoanthids growing on the back wall and on the return loc lines.

Please post comments/suggestions. I hope that there is a live critter or fish i can buy to help with this issue. I would think something in nature eats them......thanks

The fish may help but its iffy. I beleive any iof the corris wrasses will eat them..

Google "Flat worm Exit for nudis"
A Lot of people are successful with a 2x dose of FWX.
Personally I would not go that route.

I have them at one time and ripped all my zoas out and did multipl dips.

Kill the mommas and the eggs will hatch in a few days then treat again.
I treated every 4 days for 2 weeks. I used Revive then Melafix. Alternating between dips.

Good Luck!

I've used Flat Worm Exit at 4x the recommended dose in my zoanthid only tank. Did it twice about 12 days apart. Haven't had any problems with the nudibranchs since.

yellow coris wrasse ate all mine up.

Will doing the 2x or 4x dose on flatworm exit hurt anything else in the tank(good inverts, leather corals, mushrooms, gonipora coral)?

Anyone else have some input here?? thanks
