Where should I place my Zoanthids?

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 much light do Zoanthids need?

For zoanthids, you need at least 4 to 5 watts per gallon of light. However, tall aquariums need more light, since light dissipates when traveling through water. Most reef tanks take advantage of powerful types of aquarium lighting like metal hallides, T5 fluorescents and LED arrays.

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.

Do zoas like dirty water?

Zoas prefer a STABLE tank. Whether that’s clean or dirty really doesn’t matter, IMHO.

Do zoas need lots of light?

Wilkommen. SPS and zoas both come from many depths and light qualities in the ocean. So many Zoas will do well in high light but need to be acclimated to those conditions.

Why do Zoanthids stay closed?

Pests Can Keep Zoanthids Closed One of the first things to check for on your zoas are pests. If you notice that one by one your zoas are going down, this is a good sign. These like to stay hidden in the polyp and come out at night. Asterina Starfish should be easy to spot and they need to be removed.

Why are my Zoanthids so small?

Another common cause of diminishing or undersized zoas is salinity flux. If the salinity of the tank is not kept stable, the zoa will release aminos and sugars to regulate internal osmotic balance. If you want to minimize wasting and maximize growth keep the salinity constant.

Can zoanthids get too much light?

So many Zoas will do well in high light but need to be acclimated to those conditions. Yes you are correct, deeper water corals like more blue light.

Do zoas like high light?

zoanthids occupy every range of water depth from mere inches of water all the way down to no light, so to be accurate they are widely adaptable to most ranges of light from low to high, and should be placed in a tank relatively close to their originating tanks light conditions then moved slowly to the position desired …

How fast do zoanthids multiply?

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.

Are Palythoas 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.

What’s the best way to care for a zoanthid?

The more dull, drab or darkly colored, the more shaded the zoanthid coral has likely been. The best-case scenario, in terms of zoanthid placement, is to know how and where the coral was placed most recently (if it came from a fellow hobbyist tank, for example)–and if happily growing–try to recreate that in your tank.

How can I tell if my ZOA corals are happy?

Place zoa 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 up and are fully extended without seeming to stretch so far upright.

How often should you feed a zoanthid coral?

For the fastest growth of these corals, it is recommended that you feed them periodically with an appropriately sized food, although feeding is not usually required. Target feeding these zoanthid coral polyps is fairly straightforward.
