Zoas nudibranch

[clownfish_forever]

Hi bros,

I suspect my tank is getting infested with zoas nudibranch. I tried dipping the suspected rocks and colonies in freshwater for 5 mins. But didn't work. After some days, colonies are closing again.

If the zoas are all consumed, will the nudibranch die out after some times? I am thinking of that before adding new frags

Thank you.

Had that problem also. Went to get a six line wrasse and it solved my problem. Can dip in coral rx also But it doesnt kill e eggs so will still come back

I had a adorned wrasse that do used to keep pests away. This time not working

I just read that Flatworm Exit can kill these nudibranch but some said not so. Anyone can share experience? Thank you.

six line doesnt work for nudi ... TLF Revive dip is more effective than coral-rx from my experience ... u can try long nose butterfly mostly work on nudi but after settle all nudi possible will start nip on brain coral ie: blasto, acan, favia etc depend on luck ...

I tried flatworm exit doesnt work. 6 line probably like all natural methods might or might not eat e nudi. Mine did

Fresh water bath is best.. You should extend it to atleast 10mins.. You can see brown particle floating out.. Zoas are relatively tough corals.

When you fish for love, bait with your heart, not your brain...

I used flatworm exit, but u cannot use the recommended dosage as that dosage is for flatworms, nudis are hardier, usually i use 1.5 to 2 times stronger dosage.

FWE is reef safe, however if u have a lot of nudis, when they die, they release a toxin. so what i did was to get ready a bag of activated carbon after the dosage (Do not put in the activated carbon at the start, put it in after about 15 min, this is to prevent the activated carbon from reacting with FWE)

After dosing, I noticed a lot of those small brittle sea stars getting knocked out, ad started floating around, they seemed to be affected, but after a day they returned to normal.

The following was my dosing regime

Day 1: dose

Day 2: water change (to remove excess toxin that are not removed by activated carbon)

Day 3: dose again (in case of nudis who were hiding and not exposed)

Day 4: water change

Day 5: fresh water dip the zoas

Day 6: Rest

Day 7/8: Dose (this dosage is to target eggs that were not hatched at the time of your 2 previous dosage, nudis eggs are like Tim Howard, they block every @!$@$ hurled at them)

Most of us thought FWE doesn't work due to the fresh batch of nudis from the eggs.

This was my personal experience, I had a successful battle. After this, I became very vigilant in QT process, especially when it comes to wild colony. QTing zoas are easier, you can put them in your refugium (assuming that you have a sock between your refugium and return) or any compartment before your sock. Zoas are hardier, they can tank a few days without light. During QT, you can FWE/ FW dip them and observe them, you should also deliberately look out for eggs and scrap them off with toothpick.

After all this is done, you go pray.

Note: If you want your wrasse to actively hunt them and eat them, you have to be very discpline and not overfeed your wrasse with good stuff, nobody eats primary school canteen leftover chicken after you have tasted KFC bucket.

Also some wrasse are better at eating primary school canteen leftover chicken than others, do checked with the fish gurus here like bro Fuel

Why use flatworm exit that nothing ralated to nudi ?! Revive are good enough to remove nudi in not more than 1min ...
