zoa advice

I recently had 2 tank issues: Removed a single paly head that I believed was dying/dead (I wasn’t 100% sure if it’d died but I was concerned it could harm my other corals if it was dead) Treated flatworms with flatworm exit I then noticed my tank start to decline rapidly (😭) all of my zoas and...

I put this frag in and it was open and seemed good for 5 weeks, then it closed maybe annoyed by hair algae but mostly I've been able to get rid of the algae, but they still have not reopened for 5 weeks now. Can anyone see anything in my photo that might cause them to close, water parameters...

We picked up a zoa from our LFS and later determined that it might be a People Eater (Zoanthus gigantus), maybe a Red People Eater. Any input on ID would be great. It has some white spots/streaks on the discs and whitened skirt on most, but not all. When we bought it, some of the white was...

Hello everyone, I wanted to ask you guys for some help with some orange zoas I have. I’ve had these guys for quite a few months ago and they seemed to be doing fine. They grew quite fast as when I bought them I only had 2 heads now I almost have 10. For the last few days for some reason...

Hello everyone, i finally added my first softies. I did my regular water test today and my po4 was at 3mg/L. NH4, No2 No3 were all normal, but phosphates are high. All i have is 2 clownfish, 1 hermit, 1 astrea and 2 zoa plugs and one disco in a 250l+46l sump tank. I installed a diy refugium with...

Dear All, I need your help. I have a problém with Zoanthid Hardening. It mainly happens to some of my Paly (green people eaters) but also for some classic zoa as Rasta. They look good, but some pcs from the colony close, and they become hard. I tried to clean it by brush, I tried to dip it...

I have a 15 g reef with macros and softies, under white light because i like the more natural look. I have some zoas and they are fine on the bad day and great on the good one. But the problem is, they are either brown or yellow-orange-green. The small ones are more colourful , but the bigger...

So my zoa has been closed up like this for almost a week. My ammonia was just slightly elevated, but with a small water change everything is back into parameters. It did get knocked off into the sand which is what all the white is. We do have some long hair algae growing, and had our first...

Hi All, So, I have a clam shell that is completely covered in Zoa's which looks great, HOWEVER, it's also home to some mean Aiptasia that I can't seem to kill with superglue or Lemon juice. It seems to be the only place in my display tank that I have seen any Aiptasia. I have a peppermint and...
