Zoa eating Nudibranchs

[silverA3]

So I found a nudibranch munching on one of my colonies of Rastas, he was fairly good sized, about an 1/8" long. I was able to grab him with a pair of plyers and yank him off and out of the tank. That was a couple days ago and now I am seeing multiple small ones on some of my other colonies.

What is the best way to get rid of them? Luckily all my zoos are on one single rock so I can just pull it out to treat it.

Has anyone successfully rid their tank of them?

if you can take it out to do a dip then using something like Bayer diluted in tank water seems to work for a lot of people to remove pests, some even do a blend of Bayer and Melafix but I dont think it is necessary to do both.

I have been keeping an eye out also as I found one on my front glass, but I havent seen any zoos being eaten and havent seen any more since I flushed that first one so I am hoping I am really lucky.

Make sure all the zoos are closed and dip in freshwater.

Freshwater Dip *Caution*

This procedure is not recommended for palys or protopalys, as it can result in melting.

Preparationrepare a container of fresh water (preferably RO water), by adding a buffer (baking soda works fine) until the pH matches the pH of your aquarium, and raising the temperature of the freshwater till it matches that of your aquarium. A light concentration of Iodine (approx. 4 drops/gallon) may also be added to the water as well (Lugol's, Kent Marine's Concentrated Iodine, or Seachem's Reef Dip).

Dip the polyps for 3 to 5 minutes, swishing them aggressively throughout the dipping period. Rinse in a separate container of aquarium water and return or place in the aquarium.

Freshwater dips may be effective in removing various pests and for treating some diseases in the beginning stages. Be advised however that it does stress the polyps themselves, and thus is not usually recommended for use with polyps that are already unhealthy.

** Revive ** is an antiseptic and is effective in treating bacterial infections, nudis, and flatworms. It is also an effective preventative measure for damaged or fragged corals.

yep, Revive is what I use to dip right now....and all my coral additions get dipped before going in which is why I was surprised to see a nudi in there. I did see it say on the bottle it is good for fresh frags and I used it to dip a sick acan. Seems to work well. especially for like $6 a bottle on amazon.

It's been said it kills the adults faster and does require additional dips for eggs. Hit or miss I guess..lol!!

I also use RX

Yes have seen some in the LFS. Make sure you are diligent. Good luck

Alright, I'll pickup a couple different dips and see what happens. Will it be ok to dip an entire rock? The rock is roughly the size of a football and just covered in zoos.

I'm at a loss as to where they came from, haven't added anything to the tank in months, total bummer.

Thanks for the all the tips guys/gals.

Dipping the whole rock in dipping solution, not sure!! I wouldn't!! But in RO water don't see that being a problem unless someone else can chime in

I've ran mine under straight tap water for everything from zoa nudis to when they look like they might be melting and haven't lost a colony yet. But lately I have been using bayer as a dip on any new pieces.

The only downside I can think of is if the dip kills the benficials that are on the rock besides the zoos, could possible kill pods, worms, bacteria but I am not 100% on this with Revive, Bayer I would think would kill everything good and bad since it is an insecticide.
