Where should I place my zoanthids?
Place zoanthid corals in an area of low-medium to medium-high flow. Too much flow may make it hard for the polyps to open. You will know your zoanthids are “happy” if they open and are fully extended without seeming to stretch too far upright.
Which zoanthids are toxic?
Palythoa species
These decorative ornamental corals are commonly called ‘button polyps’, ‘sun polyps’ or ‘zoas’. Species of Zoanthid coral (e.g. Palythoa species and Zoanthus species) can contain a highly toxic, naturally-occurring and potentially lethal substance known as Palytoxin.
How do you know if zoas are happy?
If they are satisfied where they are, they will open up. I have found that more damage is done in the first few days or couple weeks, by messing with them, ie moving them around.
Do zoas like high flow?
Ideally, your Zoanthids should live in a low to medium-high flow area. If placed in too high of a flow area, polyps will have a difficult time opening, which stunts its growth/development.
How do I make my zoas brighter?
Try placing some zoas in a little shade for a couple of weeks and see if there is an improvement on the coloration. Your Zoas may bleach if you have too much lighting.
How many hours of light do zoas need?
Zoanthids are photosynthetic coral, however they do not demand nearly as much light as many other corals. For best growth and coloration, blue and actinic color lights are ideal. Aiming for roughly 8 – 10 hours of full light, and 2 – 4 hours of ramping up/down will typically satisfy most corals, including zoanthids.
Can you touch zoas?
Usually corals, even zoanthid corals, are safe to handle.
Can zoas sting you?
I’ve grabbed rock before in my tank and it has these sharp small tubes and its hurt but didn’t make me bleed and later it would sting for hours. I’ve touched many zoas and fragged them before and never been stung before.
Why are my Zoanthids stretching?
In my experience zoas stretch to obtain a missing element, whether that be nutrients in the water or light. Low flow can lead to stretching, high flow will lead to elongated lashes/skirts.
Do zoanthids like high light?
Valuable Member. One of the biggest misnomers in this hobby is that zoas do not like light. Zoas are generally found in shallow pools and have been measured in water where they are receiving 800-1000 PAR.
Why are my zoanthids losing color?
Under too much or inadequate lighting parameters, often times, Zoas and Paly’s will dispel and collect a different strain better apt to handle the change in the corals surrounding. Because of this, many times coloration and/or design/ pattern will be different after this transformation.
Do zoas prefer blue light?
Yes, zoas kept under largely blue lights will have better coloration. I went to see my friend’s home aquarium business and he runs all blue LEDs on his zoas to make the colors pop.
