Signs of Zoa Stress and How to Fix It

Recommended Posts

Signs of zoa stress and how to fix it..


1. Too much light or being trampled by hermits and snails they will close or look squished, maybe bruised. You want to move them to a darker lower spot or on a ledge that a shell cannot travel to easily


:The red Zoas were in to strong of light and just the centers are showing, the bottom ones are all shut on one side, if these happen rearrange them until they reopen again

:Either partial shade or lower down than before, sometimes if they reach to tall and look like trumpets it's to little of light. The far right is the same morph in proper lighting


2. Algae can be the death of Zoasa345ddff74d4e1631dab05e0f3650387_zpsxm1s

: you want to put it somewhere snails can graze, and get a clean up crew that eats the algae if you do not have hermits or a Seahare does great with green hair algae.

: if the CUC isn't touching it, pull the algae out with your fingers if it's long enough, or frag up the zoa and clip off the rock surrounding the polyps till you have separated the polyps from the rock and reglue to a new clean live/dry rock


3. Being stung by coral or worms, Sometimes you get spider webs inside the tank or so etching is eating your Zoas


:The God or wars (right) are bleached and closed up, maybe have brown or black spots on them from where the Vermitid worm's spider web is stinging them, or maybe it's a sweeper from a coral it will look like this

: super glue up the source of the spider webs, it should look like a feather duster hole with 2 antennae reaching out, or move the coral or zoa out of sweeping range.


:This photo ^ also shows how I arrange a clear path for hermits to crawl around my Zoas and not over them, steep walls and frags on a plateau will keep them from climbing, but they need an easy route to travel on. (You can see the red skirt Zoas on the left look closed and bruised from being trampled over when the route was clogged with a plug)


:Overhangs and channels need to be built in between your rockwork, and you can build in fences to make them go around the long way, see the rocks sticking up on the left used to be the climbing path.

Good stuff thanks for sharing.  It is such a mystery sometimes when they are closed for no apparent reason.


I echo another tip you shared with me a couple years ago.  When in doubt, dip em.  Sometimes there are predators you cannot detect, but dip anyways.

Thank you for the advice mr samsquanch. I love that red tipped anemone.


The Samsquanch reference is from a show that is one of my guilty pleasures.

Well thanks for the info Squatch, like many corals zoas can have a sensitive side and usually it is simply a matter of finding out what it is that  is bothering them. 


You got the idea Softy, preventative maintenance at its finest, too funny.

      Hey everyone.
      I would make an effort to submit photos tonight of my tank however it's past its bedtime. Over the last month one of my hammer corals has been partially closed most of the time. I continuously checked my levels to be presented with perfect water parameters. I decided that its best if I give it time. Two weeks have passed now, and most unfortunately my tank has spiraled into bubble algae heaven. I have made 2 attempts to remove it, but even with a siphon hose and a scalpel I cannot get to all of it. Within 2-3 days it completely grows back. Today I came home to find that 2 of my 3 sps frags had closed and changed colors to a more dull tint. My rainbow acropora is turning green and another purple/green frag I have has turned a darker blue. There is no polyp extension. My other large hammer coral was also retracted, with my mushroom corals bleached white instead of its normal flesh color, though the green highlights are still prevalent towards the top.  My anemone, or two as it split a month ago, seems unaffected and continues to take up way to much space and sting my zoa's.
      My levels, as I said before are perfect under my standards. I am unable to test for phosphates with my current equipment, however I've read elsewhere that bubble algae doesn't need an influx of them to grow.
      Salinity 1.025
      Alkalinity 7.4 dKH
      Calcium 420ppm
      Magnesium 1350ppm
      Nitrate 0
      Nitrite 0
      Ammonia 0
      Tempature 80.5F
      I have calculated my system water volume with rocks to be 14gal. I've been doing a 5 gallon water change every week since I saw the hammer was closed.
      My tank is almost a year old now. I've hit many bumps in the road but this is one that I am clueless to the solution. Photos will be submitted tomorrow around lunchtime. Please help.

      So to keep things short my old light (Orbit USA Pro something or the other) broke, salt corroded a wire and I was not able to make a lasting repair on it. I'm trying to find some cheap lighting I can get away with for my ~2 foot cube (Reefer Nano) and I really just want to keep what I already have alive, all softies right now. Ideally I could keep some higher light requirement stuff towards the top of my tank but I'm looking for cheap not perfect. I don't really have a hard price limit, but around $150 is what I am trying to find. I've looked at T5 setups but the price of bulbs and need to replace them relatively often turns me off to them.
      Any advice appreciated.

      Time to be reborn.
      Starting a new tank at a new apartment.
      This time it's going to be clean and smart.

       As many of you club members know we have a nice roster of reputable sponsors here on the PNWMAS forum, we don't have to look far for much around these parts. And I do enjoy giving different establishments my business, not only to increase my own aquariums diversity but so I can get a good idea of what said vendor has to offer. One of the most recent places I have had the pleasure of frequenting is a web site known as Zoanthids.com.  
       A fellow Zoa collector Mr.Bret and I decided it was due time for a purchase and pulled the trigger on an order from the fine establishment. I had frequented the site many times but never made the actual buy, until recently. 

      Very interesting shipping methods used here. Triple heat heat packs, wrapped, on top of styro peanut insulation, all inside a thick styrofoam container.

      Within the shipping container was yet more containers in place of bags, each labeled with the name of the precious contents within...Mmmmm, Double Trouble.

      After unscrewing the lids of the zoanthid compartments there was yet another form of insulation and protection for the polyps.

      This little guy isn't going anywhere!

      Pretty nifty idea right!?
      As far as my purchases I had to have the Sun drops, Temptations, and Fairy Tales and Bret got the Monarchs and the Double Trouble zoas. We had only ordered one polyp of each but every frag we received was at least two or more heads. And, to top it all off  there was Two bonus freebie frags included in the order that we had no idea were coming. So Cool!!!
      I am giving Zoanthids.com a thumbs up!
      I need to get some pictures of the polyps with a decent camera, some of these are intricate and need a macro shot to truly enjoy them without being here in person...Bare with me here.
