What's on my zoas?!?!


LbulletM

Recommended Posts

Little less urgent than the title would suggest, but I found these on my zoa frag last night. I didn't notice them when I first got it, though the flesh was missing in that area. Got it as a Christmas present and wasn't set up to dip yet (going to Lowes after work to grab Bayers and dipping tonight), but didn't notice anything upon initial inspection. Polyps look great - great coloring and full extension. You can see the one on the frag and a couple more on the plug. They almost look like tiny vermitid snails, but searches lead me to think they could be eggs?

Here's them not being there when I first got it:

The little spiral things? Spirorbid worms... they're harmless hitchhikers. Also, it's not unusual to have the mat of a zoa change its shape over time. As for the little grains of crud on the stalks? Well, that just looks like grains of crud stuck to the mucous on the zoas' tissue. They'll shed it periodically if you've got enough flow.

 

Looks like a nice starter clump of them!

Thanks guys! Was worried that they were eating my zoa because of the area in the middle between the polyps. Is that normal? I thought it was missing flesh. Probably won't dip them tonight then, since they seem content! Should I at least remove the one in that area, or should it be fine as well?

 

And yea, awesome clump for $20! 6 polyps and my first addition!

It is. Likely as not that clump of missing tissue simply hasn't grown yet... the base "mat" tissue kind of grows like candle wax drips.

 

Unless you get a polyp that looks like it's rotting away I wouldn't do a thing to 'em.

Thanks! I can sleep easy tonight. ;-)

Take a turkey baster on blow on the zoas, if the white spots don't come off it could be zoa pox.

 

I think it's definitely the spirorbid worms. They have the very distinct spiral pattern,

Agreed - I had zoa pox once (treated with Furan2) and it looked like roundish white lumps on the "stems" of the zoas, not these hard little spirals on the plug itself.
