Have any of you dealt with these before?

Holy Beans what a nightmare.

First off, I have a 20 gallon tank 4 T5 HO's, a ten gallon sump, and about 10-15 diffrent zoo's with a small amoount of SPS and mushrooms in my tank.

For the past week three of my zoo colonies were not opening up for e and I could not figure out what was wrong, my ALK was a little low but I didn't think that was the cause but I added an alkalinity buffer anyways, with no change to the coral behavior.

The next day I saw a bunch of creepy crawly things buzzing around on my zooanthids, took a mental note of it as I saw it on zooaid before.

Yup, zooanthid eating nudibranch's it was. I began to search for a cure considering my tank is almost completely made up of zooanthids.

The first website I went too was telling me that these little buggers were one of the most difficult pests to be rid of in a SW aquariums and offered several no so 100% methods of eradicationg them.

FW dip the colony
canary wrasse

then I found another website that reccomeded saliferts flatworm exit, and then another and another.

The kicker is when I found positive responses on forums about flatworm exit with no ill effects to corals and live stock so I figured I would try it.

Thanks the heavens for whom ever invented that stuff.

I have done two treatments in two days in my tank, the zoo's have all 180'ed back to there origional glory and there hasn't been any problems with my fu man chu lion, blue/gold blenny, or my reef lobster.

I did however lose bristle worms, copopods, spagetti worms, maybe a few certh snails, the good little brittle stars, the annoying white starfish, and 100%(i think, knock on wood) of those vile little nudibranchs.

two thumbs up in my book. All the losses were acceptable in my opinion
thanks you salifert
 
Coral RX works great. Just gotta dip every single zoo in your tank every day til you no longer see nudis. Look VERY closely at the polyps when closed for the eggs. They look like little spirals, about the size of the flat head of a pin. Use a tooth brush or a fingernail to scrape them off while dipping. I don't remember the number of days it takes the eggs to hatch, but this is why you need to dip everything every day for like a week or two.
 
That is fantastic news man. Glad the fw exit worked for you. Loving some critters in the process is a shame, but well worth the sacrifice compared to your zoanthids.
