i was thinking half a grain of rice for some reason.  not sure what they are.

IMO if you dip them and you kill good pod/critters.  they will grow back.  if you dip and kill bad stuff.  well youre making progress.

If it was pods, what are they doing crawling on the zoas?

They're not opening, and there is something on them at night. Sounds like something is munching on them.

Bayers dip MIGHT help. I've had zoa eating nudibranchs that bayers did nothing for. I highly recommend doing a bayers dip and getting a hungry wrasse and seeing if that helps at all. Doing a dip at night when the critters are out might be the best idea.

What is a good dip for Nudibranch's? Other threads on Reef Central say Coral RX.

I can tell you this, I have looked at a ton of photos on the internet of Zoa eating Nudibranch's and none look this small or nondescript.

Flatworm eXit worked for me with Zoa eating Nudis.

I'd dose the entire tank. There are more in the tank than what you're seeing on the colonies.

 I would rather try and dip just the Zoas that are in the tank. They are all on removable rocks. Just don't like the idea of dosing a tank this young. And Bayer would kill my crabs and snails I thought. Or do you mean to dose the tank with flatworm exit that mike recommended?

Flatworm exit. Don't dose the tank with bayers, that would essentially start your cycle over.

I use it as a dip.


I have also used it to treat small tanks at a 4X dosage but I don't really recommend this as it kills of a lot of other microfauna in the tank too.

IMHO the best way to get rid of them in a small tank is to look for them morning and evening on the zoa skirts and remove them. If you find them on the skirts then touch each polyp to get them to close up and check the stalks too. They normally take on the color of the skirts so can be hard to spot. Once you think you have gotten all of them then check again 10-14 days later (if memory serves me) to get the newly hatched ones too. Eventually you will win. If you do find them on a colony that can be removed from the tank then definitely dip it then inspect it under a magnifying glass and bright light.

What you're seeing are probably just seed shrimp (Ostracoda). They're typically harmless...most people rarely see them since most fish love them. If you don't have a ton of wrasses or other similar fish, they can live in massive numbers. My fishless tanks turned almost solid white at night when they came out.

As for the zoa issue, a picture would help a ton. Otherwise, most of the suggestions are valid.

Any more ideas why these two frags are not opening? The picture show what they look like during the hours the lights are running.

They look fine, probably just adjusting, leave them alone and stop messing with them unless you have some reason to believe you have some pest but if you have dipped already would be surprising. I have hundreds upon hundreds of zoas and at any given time some are closed for days at a time, if its 2 or 3 weeks and they have not opened then I would be worried, if they begin to melt, I would be worried, if you run carbon and its not rinsed properly or its tumbling/flow is too fast and its grinding then that can irritate them as well same if GFO is tumbling too fast. I have the below patch and sometimes sections close up for days or week or so, but they always eventually open back up.

These two colonies had been open for over a month in my tank. The closed and have been closed for almost three weeks now. I did stop GFO for a week no change. I run my GFO and GAC into a bucket using RO water before I put it in service. I don't tumble the GAC and just a surface tumble on the GFO. 

They are not melting, as a matter of fact they are still making more heads. That is what I is weird, they don't open but they are propagating.

 It is not that I am so worried but these are two of the zoas the wife and I like the most and they don't open. Plus if this was an early stage of something it would be nice to catch early.
