Hitch hiker

[Welly]

Hi , I just found out that my tank has alot of these hitch hikers.

Please help me.

I am a newbie here and please tell me whether this is reef safe.

If it is not reef safe please tell me what to do.

These are zoanthids. Soft corals. Part of the reef.

How to remove them bro ?

[Welly]

I am talking about the ones on the zoas

[PowderTang]

Try to remove them and coral dip

[iskay]

Those are zoanthid eating nudibranches. Dip your coral to remove.

If that coral had been in your tank, they probably had spread now. If so, keeping your tank coral free to starve them off.

There is more than 40 pcs on all over the tank

[Welly]

Do they only eat zoas ?

[pcw]

Yes only zoas. Dip your zoas. Even a quick freshwater dip is better than none at all, assuming you don't have currently have coral RX or smth like that at hand.

I read somewhere that if u are hardworking, pinching them out of the water with tweezers would do the job too. But that's provided u can pinch out 20-30 at a time, greatly reducing their reproduction rates.

A few lone individuals won't be able to reproduce. So as long as u maintain the hardwork it should be cleared

[Evolutionz]

Nudibranches, I assume u do not have any dip with u right now. Do a fresh water dip for about 10-15 mins.

[Clement Chen]

Used to have them too. My 6 lined wrasse finished all of them. Best is to dip and get a wrasse. Dipping wont completely remove them as they might be in ur rocks n sand..and dipping also wont kill the eggs

[Welly]

I dipped all my zoas for 5 mins yesterday.

May I know where can I get the mediaction that I can put in my Display tank ?

[Clement Chen]

Not really much u can add. Some ppl says flatworm exit can kill nudibranch. But doesnt always work

[Welly]

O ok , lucky it just eats zoas.

And my zoas not those expensive ones.

[Edmund Koh]

Haha better get rid of it. Else one day u decide u want to put expansive Zoas but u cant

[mitchell.liang.9]

Maybe what u can do is get those external breeder box and put your zoas inside after a good dip. This way higher chance for those in the tank to starve out and easier for you to monitor the zoas and pick out any visible nudibranch

Ok thx will try the method

[tench1]

Welly, the most effective method is to use natural predator against the nudis.

Get ur tank a 'policeman' aka yellow Cories wrasse. There are many other wrasse that works as well. But this is the more cost effective specimen you might want to try first.

Add the affected zoas colonies into the breeder box that Mitchell spoke of. Add the wrasse into it.

Only remove the colonies after all zoas beautifully open up.

Welcome to reefing world!

Ok will try buying some wrasse .

My zoas has opened up 1 day afyer I freshwater dip and there is little nudis left

Do monitor that pcs of zoas again as it might have eggs and nudis will appear again.

If I cannot get rid of the eggs what else can I do? I have the same problem with a few bunch of zoas. RODI them for five minutes and wash the zoas under running water already. And find out after a few weeks those nudis still appear.
