The Zoanthus Troubleshooting Guide

[@ypreston7534]

this video was perfect timing! thx for the help, I literally was looking for a video just like this because I didn't know what cause was so I was just trying to get started in the right direction. Thanks for making these videos because they are really helpful.

[@fuffoon]

I am just amazed at what you have done with your business. From a greenhouse into a beautiful purpose built structure. Much admiration.

[@tidalgardens]

Wow, thank you!

[@fantasyskeep]

Can we get a flowerpot troubleshooting guide?

[@carterminich5610]

You are awesome we are so lucky to have people like you who share this information...great video....I LOVE ALL YOUR WORK!!!!

[@pete4778]

Just received my shipment of assorted corals very professional shipping and packaging . Everything arrived in excellent condition and are thriving. Thanks

[@jcbrown5775]

This is awesome. Can't wait for more videos like these. Thanks Than and team!

[@tidalgardens]

Thank you. Glad you like it.

[@AndyMahnFL411]

Great content. Having learned that the risks do exist, I have found a solution to be to grow zoas out in a separate tank and then will transplant a few test polyps to the main display aquarium. This serves to safeguard the original colony and can certainly save a few $ in case things go south due to predation or other causes. Oh, yeah - 658th!

[@Jolopy8000]

This is a top quality guide. Its cover everything, thanks since I just loaded up on alot of zoas!

[@tidalgardens]

Glad to hear it!

[@Waynerock77]

Man my cheepo’s (alpha omega, utters white Z) grow like weeds but my expensive guys (LSOH, Vegas strips, halls) grow to the tune of 1 polyp every 3-4 months IF that. I guess it’s the pretty ones that make you work for it. I tell you a target dusting of reef roids and dosing Iodide has definitely helped with growth and color. Amazingly done video an usual Than! Wish everyone took as much care with quality and narration as you do.

[@tidalgardens]

Thank you. Good luck with your zoas.

[@josemiguels7688]

would be great to have a mushroom troubleshoot. I often get mushrooms that just lose colour

[@meghancampbell4005]

Thank you I will try the paintbrush cleaning!!!!

[@FranklinDattein]

Euphilias are the most regular cause of trouble for zoas, in my tanks. Detached hammer polyps land in the zoa colony and release a toxin that slowly spreads to the entire colony. Polyps close down, them turn black and finally melt. It took me years to identify it, because the culprit is gone by the time the colony starts to perish.

[@MrKea009]

Please make more videos like this one especially about zoanthus

[@drugmonkeyrx7965]

Good stuff man! ....had no clue about the brush off method

[@tidalgardens]

Glad I could help!

[@fishpony1211]

This is such a great video! I have a small colony acting “weird” im going to look into these things

[@tidalgardens]

Thank you. And yes, a zoa colony doesn't just look weird, usually there is something wrong.

[@mraquaticnews5676]

Very interesting! Good upload

[@sanpietroprogettista9887]

Thank you!

[@ZoaLove]

Amazing content. Great Video and all said.... Greetings from Germany ☺️ I totally agreed with foxfaces. Mine got me rid of my single polyps too. I guess they where new to him and he got a bit and they all where gone over night. All bigger colonys are safe.

[@tidalgardens]

Sounds very familiar. Good luck with your other Zoas.

[@martijnvanbeek4387]

Thank you Than, another beautiful episode in your series! I was kinda hoping you'd include some info on paly toxines as well because I would consider that as Zoas troubleshooting too:) I recently had a Nero 3 pump making a lot of noise in its new place in the background so at the end of the day I took it away, but accidentally I tore some zoas apart. Got quite sick that night, vomiting etc. If I had seen that zoas had been tied up in the pump I would have used my gas mask with biological filters in it to get rid of it. After a day I had cured quite well. And these zoas weren't by far my most toxic ones. I try getting rid of them by using AiptaCap in them. Never put zoas that will grow fast on your rock structure people. You can't just go about slashing and cutting them away if your health and those of the fish and other corals is dear to you.

[@billysprout2374]

i am so glad you're feeling better!

[@Ellery-USA]

Great video as always!

[@tidalgardens]

Thank you!

[@RogueAquariums]

Some good information Than. Very helpful. Thank u

[@tidalgardens]

Glad it was helpful!

[@RogueAquariums]

@@tidalgardens it was 😊 I too learned the hard way about introducing single polyp zoas in the tank.

[@dopeameanreef6221]

Thank you for the video

[@tidalgardens]

You're welcome

[@cripnikka86]

You didn't mention hydroids, idk if it's a zoanthid specific pest or not but I had an issue with hydroids growing near a zoanthid colony in my frag tank (I thought it was a filter feeder until I reinspected it again. I had no idea where or how did they come from, but thank God it was only 2-3 small hydroids), they made some zoanthid polyps nearby closed for a couple days until I realized there was something irritating some polyps. I killed em with a tweezer lol and the next day those closed polyps started to reopen. I also had an issue with GHA a long time ago. Small patch of GHA started to grow in the middle of my zoanthid colony, and made them closed. I pulled it out, dip it with 3% H2O2 dilluted with saltwater 50:50 for 2 min. GHA turned white and the zoanthid started to reopen again. Nice & very informative video btw ^_^

[@xisotopex]

how did you identify that it was not a filter feeder? I found what looks like a very small teeny tiny pulsing tentacles kind of like a feather duster worm maybe? but very small.

[@OCReventsAndbuilds]

Love these info videos ❤️❤️❤️

[@tidalgardens]

Glad you like them!

[@RobBoryckiGolf]

Thanks again Than great video

[@tidalgardens]

Glad you enjoyed it

[@davidhughes7180]

Thank you for sharing! Do you have any tips for zoas that are losing colour on their skirts? Discounted usual suspects (lighting, nitrate/phosphate)...

[@jamesbrewer6789]

I think I fresh water dipped all my coral on the move to my new tank, it wasn't warm water either. Everything was open within two days. Zoas, lps and sps, maybe 10 minutes tops?

[@MrBestshot33]

Seem to work well?

[@tidalgardens]

do not recommend

[@patyczak1000]

Maybe episode about FW dip would be nice idea ?

[@jamesbrewer6789]

@@MrBestshot33 i was aimming for aiptesia, it did not remove them, but it didnt kill the coral either🤷🏼

[@teesky8456]

I having troubles with my zoa from last month my nitrate outbreak about 40ppm after I solve it my zoa look kinda weird most of them was extending become longer like tentacle and not fully open. Any idea?

[@kjeldlarsen912]

Thx

[@tidalgardens]

Any time

[@Edgecrusher28]

I have begun to routinely clean off all my zoa frags with a blast of tank water. I have noticed some of my frags will always release thin white layers of what looks like skin or flesh. I thought maybe it was a form of sponge, but it really doesn't appear to be that upon further inspection. All of these frags have great flow, but ultimately not very happy. NVM, looks like this is the wax layer mentioned in the video!

[@tidalgardens]

Thanks for sharing!

[@beaubaker4222]

I bought some rastas yesterday and dipped them but when they started opening in my tank the middle of the polyps lost all color and pretty much turned black. Any idea? Thanks

[@xisotopex]

will an "extra" soft toothbrush be soft enough to clean the zoas?

[@gabrielhan3533]

Do one zoa umbrella syndrome

[@gokuthetypeofningen1688]

I have one frag with keds reds and Green Bay packers that has been dying off and my rastas have been looking skinnier and skinnier too, but my utter chaos and purple monster frags are happy Idk what I did other than leaving the frag stuck in the sand bed

[@jluusaltwateraquarium8320]

Hello sir I have problems inside my tank I have alot of colin's that all gone should I take all my rocks and corals out and take all the waters start over again is that the best way to do....

[@vanderburg.M]

One thing I wish you covered was coraline algae. I use to have one of the nicest zoa gardens in NZ but it's slowly being destroyed by plating coraline algae. Seems like there is nothing I can do to prevent this.

[@tidalgardens]

That is true, there are some very fast growing coralline algae out there that can cause trouble with Zoas. Coralline is one of those things that is the lesser of many evils. They prevent other worse algae and look nice but they too are fighting for the same real estate as our corals. A lot of them though do not like high light. A brief boost in light, maybe only a day or two might kill some of it off. Worth a try anyhow, just don't kill your zoas.

[@therallybeard]

From 4:08-4:11 it showcases coral that has a few flowing mini sweepers or hydroid that look like they are swaying. Very tiny more on the right side of the screen, looks like a small tube with a flower head that sways in the flow. Can anyone identify these little things? I started to cycle a nano recently and have seen a few travel from some rock and now are clinging onto the back of the filter where the screen is.

[@SlashPlatinum]

So my zoas do good for about a month then they slowly start to shrink and lose they bright color and then they’ll barely open

[@zachary_smith1]

Will Dino’s keep em closed?

[@89Johneboy]

Hey! I know its a long shot but i have a question... I bought a colony of 100 or so polyps and they haven't opened since i received them 2 weeks ago =( . A few of them did a little peek, but not fully open for the first few day now theyre mostly all closed =( My parameters are all good and this is my first coral. 2 month old tank with 2 clowns. Amm 0 Nitrite 0 Nitrates 12.7 temp 77-78. I have good flow, ive adjusted their placement to try higher and lower areas... still nothing =(

[@eastnjman368]

I had some blue legged hermit crabs that ate my Zoas 😭

[@XXZombieXHunter]

Can someone tell me the name of the zoa shown at 30 seconds in?

[@billysprout2374]

love itttt

[@franciscoaguilar7505]

I had a nice zoa garden but 2 years later suddenly they all melted away.

[@crath3570]

Any suggestions to kalk ato lowering Ca and alk?

[@baaa4698]

Lowering?? Kalk should be raising those alk and ca numbers, no?!

[@crath3570]

@@baaa4698 Kalk is calcium hydroxide. I’m pretty sure the calcium in the kalk was reacting with dissolved carbonate ions and precipitating out of solution as calcium carbonate. This in turn lowered alkalinity and may have lowered the calcium with it.

[@spicyreef]

My filefish take care of all the zoas that try to peek their little heads out, agh!

[@tidalgardens]

I've never had a file fish but it does not surprise me that it wants to eat coral.

[@onlyfins7729]

like the video but was not keen on the music at the end

[@ParteVerdeA]

What can cause green hair algae or short black algae?

[@planetarybeat473]

A lot of things , you need to test your parameters with a good test kit and go from there

[@ParteVerdeA]

@phuture thank you i tested phosphate and it reads normal levels so it must be nitrates

[@jahsreef8386]

Peroxide dip only thing missing imo

[@tidalgardens]

We do not use peroxide much here as it tends to be very harsh. Glad it works for others.

[@garbermatt2]

I watched this video and almost killed my tank by trying to "POP" my closed zoas after cleaning them off. They started releasing toxins and I stopped before they poisoned anything, but all the other corals started to react :(
