Help with zoa-eating nudibranch

andreasch · Nov 30, 2018

Hello,

Since last Sunday my zoas suddenly it fully closed. I was trying to find the reason and it looks like is cos of zoa-eating nudibranch in my reef tank as i found like 15 crawling on my glass.

I took my zoas out of the tank and dip it again but nothing changed. Is still closed. And i know there are many nubis all over my tank. So i need a reef safe way to clean my whole tank from these pests. Any livestock that can take care of the situation? I read about yellow wrasse. Any experience with it? Live aquaria has this wrasse in "Not reef-safe" category.. Any other suggestions on what to do to help my zoas open back?

Thank you guys..

Yellow coris wrasses...will eliminate them not reef safe cause it will consume desireable Micro fauna as well. I have one i love him.

Only micro fauna? How about other inverts (skunk shrimp, CBS, snails etc...) and corals? Will leave these alone?

Is there something more reef safe that can eliminate these nubis?

Never seen my big orange back fairy picking at anything. He does eat my snails if they are upside down. Probably thinks it's a half shell clam.

Fairys and flashers not much help. 6 lines are great bug control but they get aggressive...

These nubis can survive and make eggs in the tank if there is no zoas coral inside? I mean they can make eggs on other corals, rocks, sand etc???

Flat worm exit treatment,,do some research for this treatment before you dose it...DO YOUR HOMEWORK and make sure your comfortable in doing this treatment ..it will take atleast 3 timed treatments to kill the live ones and eggs after they hatch.
very effective but you must follow protocol..

If you remove all of thier food source they will eventually die off.

Do you know if these nubis eat also on palys? Or only zoas?

Yellow Coris Wrasse and manual removal worked great for me. For manual removal I used a turkey baster/coral feeder to suck them out when I found them. Under blue lights worked the best and a magnifying glass helped a lot. They can be hard to spot on zoas, as they pick up the colors of the polyps they are eating.

Ive only ever seen them on zoas but idk if palys were the only food they might go for them.
