Need help with Nudibranchs

Jyetman · 09/28/2013, 10:47 AM

For the past four or five days I found a single bright green nudi crawling on rocks or near some zoanthoids. One actually had the nerve and slithered onto my blue zoas. I removed them immediately and got out the magnifying glass to find more never did until the next night. So today I removed the zoa plug and did a freshwater dip for 12 Minutes no nudis came off? I'm very confused I found some eggs and scraped them off the stalks but have never found a nudi actually on the zoas? What's going on here?

Can you post a picture; that might help.

Are you sure they're nudibranchs and not flatworms? Nudi's are very specialized, cool, but specialized. They usually have a single specie of food source and if you don't provide it, they die. They are very fragile environmentally, so I might be more inclined toward flatworms rather than nudi's as your problem.

Don't think it's a flatworm this is similar to what I saw crawling on a rock wasn't on any zoas.

Have you seen little round marks on the zoas when there closed up? If so that's where the nudi's are biting your zoas.

No that's just it I took out all zoa plugs and did a fw dip no nudis fell off? Only found eggs on a dark brown colony and besides this green nudi the next two nights I found a single dark brown nudi crawling up the glass near that brown colony. I figure the brown one came from the brown colony and the green from green colony but no nudis found on either frags. I did add a monti frag from three weeks ago maybe they came off it.

I thought round marks indicated zoa pox o.o

Does anybody know if the exact nudi pictured above is reef safe? I have bubble coral, hammer, zoas, Xenia, sponges, mushrooms

No it is not. They are species specific coral eaters. http://reefkeeping.com/issues/2005-05/rs/index.php
