zoo eating nudibranch

H

harial

I did a search fro ways to get rid of them but it was all people pulling them out manually everyday for months. If these are infact the type that eat zoanthids can I take out all the zoo colonies and frags and put them in quarentine for three months and just focus on taking care of those corals? will the ones in the tank and their eggs die without any zoos to feed on?


thanks

ps same goes for the sun dial snail? which I think I also have :evil:
 
I was under some dillusion that I "would never get that pest" so I am going to pull out all my zoanthids sinch none are attached to the rockwork and put them in my extra 10 gallon.
 
unfortunately, it won't get rid of them. they would live in the sand and feed on stuff other than zoas, and lay eggs.

you can search reefcentral, there are certain wrasses that would eat them and get rid of them completely. I think MuchoReef wrote it.

other than that, you can dose flat worm exit every few days for a month. but that would wipe out your pods and would very likely kill your fish and corals too.

by pulling them off the rocks for months, you would also need to go in and scrape off the eggs as well. it sucks.

and as far as the snails, those are easier, just pull them out.
 
Flatworm exit does not kill fish or corals (may harm inverts though).... the people who have had die-off issues from it was due to the numbers of flatworms in their system and the toxins from the FW's, not the product itself.

This is what I am doing currently on a number of colonies and haven't seen a nudi in 2-3 weeks now.

Fresh water dip with lugols, flatworm exit and furan-2 for 10-15 minutes. Match the temp and ph of your tank water before doing this.

Keep zoo's in a QT and repeat this process every 7 days for 21 days.

As you dip, use a magnifying glass and tweezers to pull the egg sacs off. The egg sacs look like little curlie-cues that are white.


Long-term solutions - continue the same regime of dips each time a new zoo frag or pod is introduced.

The wrasses.... several have been reported to have success. The first reported one was a Sea Grass Wrasse. This is a seasonally available (according to frank) as is not reef safe so use with caution. They grow rather large 4-5". Others have reported success with Yellow Coris and Dragon Wrasses.
 
ok I have some pics. They arent great I know. But anyway since I have been researching these thing I have come across all sorts of nastiness that seems to decribe some things in my tank and now I am freaking out. first is this snail who's shell is in the shap of the sundial snail, however he has marroon stripes rather bllack and white checkers. I started calling him Taeni which means stripe or band in latin. Not sure if he is the bad snail. I sure hope not. He has been in there for months, I always see him.

next is a cluster of what I thought was feather dusters but could infact be hydroids. if this is the case, it is not so bad as they are isolated to one frag but this would explain why the frag has been decining.

and last is the pic of the nudi. the pic sux and he is a bit worse for ware seing as I grabbed him with a pair of massive tweezers and I was a bit surprised I had not crushed him when i got him into the bowl.
 
That snail is a trochus (zebra, banded etc.) Great snail and a good thing to have.

That is a nudi, that's a pretty good shot of it.

Sorry but I can't make out the other shot so I can't tell if its hydriods or feather dusters.
 
"According to Dr. Ron, their diet is very specialized and without zoanthids they will die off. Actually, the only sure way to get rid of them is to dip and quarantine the zo's and keep them out of the tank about 6 weeks. Meanwhile, the zo's need to be dipped every 3 days ... I don't know how long ... to eliminate any eggs."

I got that off reef central. I am going to go searching for the exact thread where he states this but I am pretty sure I am going to end up going this route. I read that they like sponges also and since I have a fair bit of those I'll probably extend it to 2 or 3 months to be sure. It sux though. I have all sorts of sponges in different colors all over my tank.
 
We battled the nudi's in Lisa's nano. We dipped about twice a week for about a month, and manually removed egg sacs after each dip. (Just a fw dip, with a vigorous shake to dislodge any worms.)
