How fast do Zoanthids reproduce?
Smaller frags tend to put off fewer new zoas than larger colonies. Some colonies may get a new zoa every day or two, others maybe one a month.

How fast do Zoanthids reproduce?
Smaller frags tend to put off fewer new zoas than larger colonies. Some colonies may get a new zoa every day or two, others maybe one a month.

How long does it take for Zoanthids to grow?
During the first few months the wild colony does not grow very fast. After a period of about six months we notice that the individual Zoanthids start to reproduce and the colony starts to spread.
How do you know if zoanthids are dying?
What are the signs of Zoanthids dying? Signs of Zoanthids dying will include things like not opening for longer than is normal, discoloration, or the appearance of melting. But, these are tough creatures, so don’t give up on them even if they show these signs.

Do zoanthids need to be fed?
Like others had said, you don’t need to feed them as they will feed off light, water, and fish waste but if you want to feed them make sure you feed as little as possible. It’s very easy to get too much nutrients in the water and have algae blooms and poor water quality.
How do you stop zoas from spreading?
Senior Member. Put the rock on an island in your tank. Or if its on multiple rocks, cut off the places where it is on those rocks and either sell em or give them away and still put it on an island, the zoas will spread werever there is rock.
Are zoas fast growing?
Some actually grow fast but dont propagate, ship well or are overly sensitive so they stay pricey despite fast growth rate. It always surprises me that utter chaos zoas are so expensive yet many people here report fast growth rates. I guess the marketing helps it stay pricey.
Will zoas grow on sand?
Any species capable of growing in so many different locations is one tough fella. Unlike other colonizing anthozoans or soft corals, Zoas create their structure with small pieces of surrounding materials, like sand.
Can zoanthids grow together?
The short answer is yes they can. One can outgrow the other and drown it out. If you see large zoa colonies you can see different ones mixed in so they can survive with each other but it is hard to say which ones won’t drown the other out. What kind of zoa is this?
Can zoas survive out of water?
I accidently left some out overnight. They were fine. Zoas are hardy little creatures. I once had an unkown clam on a piece of LR and left it out of water for probably a week then put it back in and I noticed the clam and it was open and happy.
How do you handle zoas?
You should never touch the tissue of a Zoanthid or Palythoa coral, especially Palythoa. Always handle the frag from the frag plug and the colony from the rocks underside. Always wash your hands thoroughly after handling them. It is important to wear gloves, a mask, and eye protection when fragging them.
