akambience Posted January 29, 2012 Share Posted January 29, 2012 Sorry for the terrible picture... this little slug (?) is teeny, only about 2x5mm. I noticed it for the first time today crawling around on a single zoa, which hasn't reopened since I removed the critter in question from it several hours ago. Any idea what it is?

cellowithgills Posted January 29, 2012 Share Posted January 29, 2012 You've got Zoa eating nudi's, no question. What to do about it is the real question. Link to comment Share on other sites More sharing options...
akambience Posted January 29, 2012 Author Share Posted January 29, 2012 bummer... why does it have to be so cute and how did it get in our tank! Link to comment Share on other sites More sharing options...
arredondojason Posted January 29, 2012 Share Posted January 29, 2012 probably came in with a frag you purchased or something like that i would flush him then keep an eye on your zoas and see if you see any more or some eggs, then eliminate them. http://www.melevsreef.com/id/zoas.html second one down the list of pests looks like yours.

MVPaquatics Posted January 29, 2012 Share Posted January 29, 2012 Yes. Zoa eating nudibranch. Unfortunately it seems they are going around lately. Heard about 10 incidences. Link to comment Share on other sites More sharing options...
cellowithgills Posted January 29, 2012 Share Posted January 29, 2012 They're cute and colorful because they suck the zooxanthellea out of the zoas so they can blend better with that colony. If you don't have a utility wrasse, I'd get one. I would take out all your zoas and dip them in coralrx or something similar. Have you added any zoas to your tank recently?

akambience Posted January 29, 2012 Author Share Posted January 29, 2012 yes, within the last week from two different sources. I didn't know nudi's could be a pest. luckily I haven't seen any since... but we'll keep a close eye. thanks for the advice! Link to comment Share on other sites More sharing options...
cellowithgills Posted January 29, 2012 Share Posted January 29, 2012 If there's one, there's more. Check at the base of the zoas for egg cases. Look it up on google images. Link to comment Share on other sites More sharing options...
matty Posted January 29, 2012 Share Posted January 29, 2012 If you can remove your zoa colonies easily I would dip in fresh r/o water. Put the colonies/frags in the r/o water and swoosh them around then let them sit for like 5 min. This will kill everything on the frag except the zoas and any eggs still on them. You may have to repeat this every week until all of the eggs are gone. This method has always worked for me. Link to comment Share on other sites More sharing options...
akambience Posted January 31, 2012 Author Share Posted January 31, 2012 OK, will do that tonight. It was on a frag we got from a less-then-popular LFS, I'm even going to try and pick up a Melanursus wrasse this week. I'll be sure to look very closely for eggs next time! Would a CoralRX dip have prevented this? Are there other wrasses that will do the job that aren't jumpers? because we have an open top. Thanks again for your advice!

matty Posted January 31, 2012 Share Posted January 31, 2012 Yeah coralrx would work also. Some even suggest iodine. Plain old fresh r/o always worked for me. It is amazing what will fall off the frag and die. I would only suggest getting a fish to combat pests if you really like the fish. Fish are always a shot in the dark and you will be stuck with the fish or have to try and catch it if it doesn't eat the nudis. Link to comment Share on other sites More sharing options...
dsoz Posted January 31, 2012 Share Posted January 31, 2012 You may want to consider telling the sources of your new frags that you have nudis. Don't expect a refund or anything, just let them know that they may be infected and that they may want to check their inventory. dsoz Link to comment Share on other sites More sharing options...
