A few months ago my zoa colonies were doing well and multiplying, but I started to lose some randomly. I am wondering if it is zoa pox, but also I noticed that I have red planaria as well hanging out around them. I thought maybe they weren't getting enough light so I turned up my radion gen 3s. They used to peak at 40% and now they peak at 50% for three hours a day during the cycle. Please let me know if you see anything. Here are some pictures.

Just checked them. They are at 0. This is a cycled tank that has been running for about a year and a half.

Also I do two part dosing.

0 may be the issue. I recently had this happen. I was dipping frags, peroxide, antibiotics doing everything I could. Ran my tests had 0 nitrate and thought maybe that was the problem. Turned off my skimmers fed heavy for a couple days and the ones left all opened up

Wow, no way that is not something I would have guessed! I believe it though!
I never thought a nice clean well skimmed tank could ever pose problems haha. Maybe I will increase my feedings? Should I run skimmerless for a few days?

I would try. They seem to feed on something in the water. Thought about this because of sps which are low nutrient do better with a couple nitrates, and softies like more nutrients than sps.

I lost a rock of Zoas, found out it was Zoas eating nudibranches. Dipped my Zoas a couple of times and could see the little nudibranches falling off, also look for eggs arms manually remove them

What fish and invertebrates do you keep in your tank?

Well I turned off my skimmer for a few days and went to three barrel rolls on my Apex auto feeder, but still they didn't open up or no change from the others that keep disappearing.

Well I have maybe half a dozen blue leg hermits, a scarlet hermit, and I think I have maybe two zebra hermits left. I did have an emerald crab, but I haven't seen him in months so I think he is gone now.

As far as coral I have two rose bubble tips, but they are a little removed from these guys as they are on another rock.

Fish I have a yellow tang, yellow kole eyed tang, black angel, flame angel, yellow foxface, strawberry dottyback, sixline wrasse, pajama cardinal, pixie hawk and a flame hawk, and two ocellaris clowns

Thank you!

LOL at the last tip (because I have these fish)

7. Don't Buy Animals that Might Go After Zoanthids -

- Angelfish
- Foxface (Rabbitfish)

I have not observed them really bothering them, but maybe they are the problem? I do see the angel nip on that rock occasionally, but it doesn't really look like they are at the zoas so much as picking off pods. I had these fish too when my zoas were really multiplying.

Not uncommon for them to be eating when you are not looking.

Even if they are not the problem they could be down the road.

I bought a Blue Hippo Tang and he was fine.

8 Months Later ate all the Zoanthids!

So these Fish can never be Trusted even if they seem fine now.

Are there any other corals that are effected by zoa eating nudi branchs and zoa pox? If that is ever to be determined to be the issue I will just wait until they are all gone and use that rock for Acans or something. The rock is not removable and therefore I can't treat it.

Nope.

Well that is good. I don't want to minimize zoanthids in any way because they are very attractive and otherwise such a great coral. It is just that I want to plan ahead if I can't make it work with them that I know the ramifications of anything else that I would introduce.
