Which zoas are toxic?
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.
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 zoas are not toxic?
The relatively common pink zoas are likely to be Zoanthus kuroshio, which is likewise a safe addition to your reef tank. The species most commonly referred to as “palys” in the aquarium trade are actually Zoanthus gigantus, which, if the general trend holds, can be presumed to be safe (though confirmation is needed).
What is a Paly coral?
Palythoa Coral Care Zoanthids and Palythoa are a large group of corals in the reef keeping hobby. They come in an incredible range of colors and patterns making them very popular with both beginner hobbyists and rare coral collectors tracking down the uncommon color morphs.
What’s the difference between zoanthids and Palythoas?
Many people also use different names to describe the same zoanthids. Generally speaking, zoas have smaller, more colorful polyps, palys have larger, duller polyps, and protopalys have polyps on stalks that have more tentacles than the others and they do not grow from a thick mat.
How quickly do zoanthids grow?
Most of mine grow at about a polyp every few weeks. However, I have a colony that is not invasive by nature but is growing about 1 polyp a day!
How long does it take for zoas to spread?
If you don’t really like them, 24 hrs. If you paid too much and love them, 2 years.
Will zoas grow on sand?
Dependent on the zoa, they do have the ability to mat across the sand, although they don’t really bind to it like they would rock per say. Growth rates will however be slower than on the rock. Stick to rock and hard surfaces.
How do I get rid of zoas?
They look like zoas to remove you can just pull them off the rock. I do recommend gloves just in case of the palytoxins I’m fairly certain they will release them if you just rip them off the rock.
How can Palytoxin be prevented?
Some additional tips for avoiding palytoxin poisoning include:
- Washing off any potentially contaminated surfaces after maintenance.
- Taking care to keep from splashing tank water on yourself.
- Positioning your poisonous corals away from excessive light or heat, as this triggers an increased palytoxin production.
