[zebradanio]

Got anybody know what is the "blue ant" on top of zoa picture below? do i need wash the zoa to clear water? because my zoa didnot open.......

[teebs]

Your zoa is infested with nudibranchs...Not good...

Try dipping in Coral RX to kill off the nudis.

It looked pretty bad. fast action needed

Nudibranch = sea slug?

i saw few very beautiful slug in GO tanks.

If i dipping in CORAL RX will kill the slug too?

Those are zoa eating nudibranchs...u need to kill them otherwise they will eat up your zoas and then move on to other zoas in your tank. Very soon all your zoas will up the lorry...

U can choose to dip them in lugols solution (iodine), freshwater or coral RX. Lugols and freshwater will stress your zoas so coral rx is the preferred solution to use.

Anyway, you need to do it quickly as once the nudis lay eggs, you will face a never ending battle to keep them off your zoas.

Where to buy this Coral RX? Can dip to whole tank?

never dip your whole tank with coralrx. remove the zoas and dip them separately. coralRX can be found in reef depot and one other LFS...forgot where.

your nudi infestation looks terrible. i will just throw the whole colony away... unless you are determined to treat it. there are many thousands of nudibranchs in the ocean. each one of them have very specific diet and will only eat 1 kind of food. not all eat zoas.. the ones you have are the zoa eating nudi.

here where's the nudibranches are.

try contacting reddevils, he might still have a few available bottles.

Alternatively, you can use Lugol's solution. There's a thread on zoas under the pest section. Details of the mix there.

its quite bad....better take it out and quarantine before they invade your other zoas...no quarantine they will be 100% eliminated with lugol dip or coral rx dip....if i were you, i frag the zoa into small pieces...easier to handle the nubis that way.

[zebradanio]

if my position of the other zoa is side by side, do you think it have move to other zoa too? or they will eat up this zoas first and then move on to other zoas?

[mengyang_neo]

Checked my tank the zoa also infested with nudibranches. I dip them with fresh water le, but i dun how to see whether there is egg or not?

i spot eggs too..

Lemon care to share how to identify the egg? Thanks.

they will simultaneously invade yr zoas...better take it now and frag into smaller pieces and place them in a separate tank or pail of SW.

i just bought one colony of zoa from GO the day b4..also invaded by some nudis...but i was very lucky to spot them and feed them to my suns and remove their eggs....

but for yr case, situation is quite bad....anyway once all yr zoas mati...they have no more food source left, they will die and disappear.
