Zoa Issue - Two Colonies having Problems

[ocncheffy]

Hey guys,

I seem to be struggling with the same two zoa colonies for quite some time now. I've moved them all around my tank, and I can't seem to make them happy. They've both grown out from a single polyp, but ever since I started up my new 60g cube in June, they have never opened much or grown whatsoever.

Below is a rasta zoa colony that had actually opened up fully two weeks ago, but are now looking like this daily. I can't seem to pinpoint this issue to any one thing in my tank. The two colonies pictured having issues, have been that way for a months.

Here is a fruit loop colony doing the same thing:

I've done coral revive dips as well, which doesn't seem to make a difference. Here's some pics of other zoas in my tank with no issues at all.

Here's the parameters:

Salinity - 1.026
Alk - 7.5
Calcium - 450
Magnesium - 1400
Phosphates 0.1 ppm
Nitrate - 4ppm

I had recently removed my biopellets to maybe curb the issue but those were only a few weeks old and most likely not working as of yet. I also dose N0304x at 2ml a day to help with nitrate and phosphate as well.

Any suggestions appreciated!

Did you check for any nudis? Are those white dots attached to closed zoas moving? Baby nudibranch? Maybe zoa pox...

I also questioned those white dots but they don’t move and I think it’s just sand that is cought on the slime of the polyps or maybe it is in fact zoa pox. How do I go about treating that?

get a temp contoller for your system,,also increase flow on them directly alot to get them opening...more flow and keep temp super stabil

I have plenty of flow and my apex regulates temp. Do you think a peroxide dip followed up with a coral revive dip would help?

That's Zoa pox. You need to treat all of them asap with furan 2. You can find instructions and guidelines here on r2r or other sites as well.

I'm almost certain thats zoapox and not debris. The easy way to check is to just blow on them with a turkey baster or scrape them off outside the tank. They'll pop like zits with milky liquid. I've dealt with it several times. It's totally cureable, but zoas have to be treated outside of tank. It's just a huge pain to remove some colonies.

I've always done furan 2 for 3-4 days strait in separate container for 30 min to an hour. (I've left zoas in furan 2 for as much as like 20 hours before with no losses. So don't stress too much on leaving them too long.) Then wait like 3-4 days and repeat another 3-4 days of treatment. Then wait another 3-4 days and repeat 3-4 days of treatment again.

You should be doing treatment well past visible symptoms. It's a bacteria so it's similar to treating yourself in that regard.

That stuff is super contagious and spreads fast so get on it quickly and agressively.

Thanks for your suggestion. I did a peroxide dip followed up with a revive dip to hopefully help until I can get my hands on Furan 2.

Dipped with Furan 2 on both affected colonies today. Will post an update if they survive.

You won't see results right away. Just stay consistent, and it will start to disappear.

Make sure you check the non-affected colonies closely for white spots at night with a flashlight once they are closed up. You'll see those well before they start looking irritated. If you treat a few colonies now, and then discover another colony needs to be treated next week, you'll be on a neverending cycle of furan 2 dips.

Yeah my other colonies look clean as I did have that thought as well. Doing a second Furan 2 dip today, then the third on Thursday. They actually start to look a lot cleaner (less fuzzy) now as well.

Not trying to hijack your thread ocncheffy but I'm also having a problem with some of my zoa's. They also have tiny white specks except mine do move.

They look very similar to what you posted (hard to be sure since they're so tiny) but they definitely are crawling around on the stems and heads of my zoa's. Anyone have an idea what they are/treatment?

 

[zuri]

pic would be helpful they might just be pods cleaning up any melting zoas

I've had colonies do this also and been through the "oh no, they have zoa pox". I feel people overreact to the white specs, but on the other hand, the dips are probably not going to hurt them. I just made sure to use a baster and blow any detritus off of them and use a soft artist brush and brush any "film" that may cover them. More often than not, they recovered. Sometimes fragging them helped also. Regarding that pic of the fruit loops, mine looked discolored in the center like that after a nitrate spike and just getting back to normal 3 weeks later after fragging them. Bacterial infections are a common problem also. Good luck and be patient.....results rarely happen overnight.
