wierd slugs in my zoos. HELP

[marcingo]

Those are nudibranch snails. They eat your zoos.

Zoos are pretty hardy so here is what I would do. It is risky but it will kill the snails most likely. Put the zoo frag (or colony whatever it is) into freshwater. Make sure the water is the same temperature as your tank water. Also dechlorinate the water as well. Then keep the zoos with the snails in the water for like 3 or 4 mins. It should kill all the nudis. I know every time I used to get zoos from someone I would dip them in fresh water and they always survived.

You might have to do this a few times over the next few weeks since the nudis might keep coming back.

Some people have been using Flatworm Exit with success.

I second the fresh water dip...+ iodine. Zoas are tough and will survive the dip but do not keep them in there for more than 5 minutes. After the dip give the zoa rock a good shake in the same dip water and you'll see all of the nudibranches (and any other invert) that you killed.

Oh, and also check for Nudibranch eggs. The dip may not kill them and they may not come off with the shake, so you'll have to take them off manually.

I will try the freshwater dip tonight. i dont know if iodine helps though, i had it in a saltwater/iodine dip for 15 minutes last night. no effect.

what do the eggs look like?

Someone on ReefSanctuary suggested this:

I'll just add, if you find more than a few, you may want to treat the tank with Sailfert's Flatworm Exit. This seems to nuke 'em real good.

My problem was so bad I had to remove all the zo's, do a freshwater dip, then a dip in a mix of Lugol's Iodine and Flatworm exit (2 drops/gal of flatworm exit). This did the trick, a couple more popped up after that, I treated the tank with flatworm exit and bye bye nudis.

hmm. perhaps i should try the flatworm exit as i have at least 30-40 of these buggers. will the flatworm exit nuke the eggs as well? man this sucks. i saw one little nudi a couple of months ago, removed him, brought him to oceans and they said he was ok for my tank. so i put him back. he multiplied bigtime.

flatworm exit is now discontinued in canada so good luck finding it. I got a box this weekend to stock up.

I'm pretty certain that Elite Aquatics has some Flatworm Exit.

best way to get rid of these guys is to suck them off when you see them.or FW dip the rocks if you can.they are aeolid nudis and if you google them theres a lot of info.Clint
