Zoa's dying - no idea why

[Reefers4U]

For some reason Zoas do not want to grow in this tank (which as been a $%^&) and I'm starting to suspect a fungus or pox or something.

I've got acans, two acros which are growing and showing decent color and various other LPS - they are all doing fine, splitting like crazy in fact.

Params are in order. In interest of brevity they were tested recently and are in order tested with either salifert or hana checkers or probe.

Pics to follow shortly.

Many thanks in advance for taking the time to read and respond.

Have you tried moving them to another place in your tank? Your clove polyps may be affecting them. They also prefer water that has a lot of nutrients in it.

Have you checked for nudis at night or any fish picking at them?

Matted filefish?

bang bang Reefer999.

Having no other clue I guessed possible pox or fungus so went to treat with fruan2.

I went to split it up because not all corals needed furan2





Lo, Behold what came out:



I picked out what looked like 4 nudis and one snail.

Probably more someplace in the tank by now or maybe eggs.

Anything eat them?


P.S. the nudi shot is stock photo from melev - isuck with a camera and couldn't get a clear shot.

Just routinely dip them if you suspect eggs. The picture you posted is the snail? Looks sort of like a stomatella which are beneficial they clean the polyps.

I had some of these also. I pulled every single zoa out of my tank and took a pair of tweezers to each one. Ended up removing eight egg sacs and found two adult nudis. Haven't seen one since that day. For me manual removal and a close eye on every zoa head beat it.

On a side note the snail is probably fine, kind of looks like a colonista snail to me.

Image search for sundial snail. It's a zoa eater. Pretty sure that's what you are looking at.

that dude was 100% sundial. I just suck at taking pictures. colonista travel on a different edge of their shell and I don't think they have the white protrusion when the snail is fully retracted.

I feel confident on the nudi ID because one was sliming up my front panel.

Anyone know if A pH adjusted FW dip will kill the eggs too?
