zoa advice

Hi, I have an issue with one of my zoas. I got it a few weeks ago. One half opened but the other didn’t. I also noticed some 2 white stringy thing stretching and moving on the polyp. Any ideas? Is it dead?

Hi. I bought this zoa colony from a LFS along with a Xenia. This is my first foray with corals. The rock in the picture was covered with Zoas when I got them but since have been withering away. They rarely open and then very little. I’ve done both FW and Coral Rx dips. When they’re open i...

Hi! Just done with a water change and noticed this. Is this aptaisa? I never had/noticed any so I’m wondering. Thanks

I have a bad GHA problem but it’s been getting under control after a long couple months manually removing as it comes in. However, I tried to scrape some off of my Zoa frag rock with some tweezers and I failed to see that there is a Zoa growing outside of the frag rock so it’s like I scraped the...

Help, had these zoas for 2 weeks now and they open in the morning fully but then close for the rest of the day. I have checked my water parameters and everything is bang on. Initially I thought they weren't getting enough light so increased it but no change. Now I've reduced the light further...

Hi everyone, on my Zoa rock, there is one very agressive variation. They are purple with a green eye. They are Zoa size but behave similar to Palys. These invasive Zoas are taking over not only the space of other zoas on the rock but also growing their mats over other variations of Zoas. In the...

this zoa has been in my tank one week or so and this worm thing started popping out of it today. Any clue what it is? Should I pull it out?

My zoas were 100 percent open and vibrant with red color. This past weekend I have noticed that they look like crap. Not really open. Almost look sick. Can someone help me figure out how to recover from this Test day: Saturday Salinity 1.020 - I am slowly raising this Phosphates .16 Nitrites...

Now that I'm keeping zoas, Does this mean that the water in my tank is toxic? Even an accidental splash onto your mouth or face would be bad? Palytoxins on my filter sock? And inhaling beside my tank is dangerous because it's leveled almost the same of my height? And every evaporation, does...

I got all of these these coral frags in October 2023 and they were all thriving, bright and happy. A few weeks later I had a big alkalinity spike, killing most of my fish and a few bigger corals. Everything got sorted, and my LFS housed the remaining frags and fish. Since then I’ve had a bit of...

Hey Everyone, I had to work for a few weeks out of town and my wife was taking care of the new tank while I was away. This is the first time that I have kept corals and was wondering if Diatoms would affect Zoanthids. I have checked with a microscope and can see the ship like shape of the...

hey yall am not really sure what’s going on w these zoas, all my other ones are opening up fine. here are my parameters ammo:0.0 nitrate:0.1 nitrite:0.0 phosphate:lower than .1 but not quite 0 (using API phosphate test) i do not test alk,calcium, or mg as this is mainly a softie tank. the zoa...

Can anybody tell me what these neon polyps are that showed up on my new zoa? I assumed it was aiptasia, but never heard of a neon type. Thanks!

I have two zooanthids and was wondering what there names are! Any help would be great! Thanks!

Hi everyone, Can y’all please help me ID these? They came with the tank when I purchased it a few years back and I always thought they were zoas but was told recently otherwise. I was told they are captain jerks. Depending on the spot in the tank the color changes. I was going to bleach the...

Hi, all, I recently started moving into coral in my 6-month old tank and have several small frags of easy corals (zoas, Kenya tree, gsp, mushroom, Duncan, and a small favia I recently acquired). 20 gallon tank with 5 fish and several shrimp, snails, and blue hermits. 480 gph powerhead, Nicrew...

Can anyone tell me what kind of Zoa this is?

Zoa has been in tank for a couple months and slowly morphed from the normal cluster of purple people eater to this abomination. What is happening? Is this harmful to the fish and other corals to leave it?

Hello fellow reefers! I have a few colonies of zoas which are doing amazing but one particular zoa has been getting smaller rather than bigger despite other corals showing no signs of stress… change in lighting is due to the lens I’m using not the actual light. Bluer photo is before, whiter...

Hi there, I am having a bit of a panic! This week I lost my main tank to a failed seal. I have a temporary tank at the moment and was in the process of clearing out dead corals - not fun. I picked out what I thought was a leather frag and brown detritus instantly clouded the tank. I removed the...

Hey all! New to this forum… I have a mini colony of captain jerk zoas and it looks like one is stretching off of the plug? Pretty neat. Curious if this is “normal” or …. everything seems to be healthy. Ive had zoas/softies for about 6 months and this is the first time I’ve witnessed this! Happy...

About a week ago I bought a zoa frag from my LFS and it has yet to open. It was fully opened at the store but for some reason, I cant get it to open in my tank. This isn't my first time with Zoas but my first time having this problem. I've tried moving it to areas with differing amount of light...

I got a big rock of cheap zoas from a local fish store recently that I'm keeping in my quarantine for now but a chunk of the rock broke off so I put it in one of my tanks to see if my Toby puffer would nip at it. For the most part he's leaving it alone, but they just really don't look like...

Can anyone help with an ID on this? LFS lead wasn’t there, but they were sitting in the corner and looked pretty cool to me - reminds me of an old lightbulb filament. Color is an orange/red on a dark almost black background. Appreciate any help!

Good evening, So story goes I received this Zoa on Sept 15th, delayed in shipping a day. Looked pretty rough along with some other pricey zoas. Very stressed but gave aminos over the week it opened up a long with the others. Never looked quite right, few weeks ago it closed again. Looks to...
