Tweety Bird Zoanthids. RARE!

Zoanthus and Palythoa are not as demanding as other corals when it comes to lighting. They can be kept under a wide variety of lighting types, and are tolerant of both low and high light conditions. It is always wise however to acclimate new arrivals in lower light areas because it is far more likely to be damaged from overexposure than starve from underexposure.

Zoanthus by their very shape invite detritus accumulation and a zoa colony that is dirty is very different than one that is kept clean. The buildup of detritus can slow a colony’s growth or even cause it to die back.

Strong water flow helps keep detritus buildup to a minimum as well as flushing away waste that the colony generates.

When designing flow patterns for this coral I like to provide strong consistent flow with short bursts of very strong flow. If you do jot have controllable pumps to achieve this it can be done manually with a turkey baster. Once a day you can squirt water at the colony to dislodge any buildup. I use just enough force to close the polyps up.

If you decide to go this route only do this with established colonies that are well attached. If you have a freshly glued frag of zoas they might get blown away.

While both Zoanthus and Palythoa polyps derive much of their energy from the products of their zooxanthellae, they do have the ability to capture prey. Palythoa seem to feed much more readily than their Zoanthus counterparts.

Some Zoanthids and Palythoa contain a powerful neurotoxin called palytoxin in its flesh that can be extremely harmful if it comes in contact with your blood stream. By harmful we mean deadly. Take special care handling these polyps for this reason especially if you have open cuts on your hands.

In practice you are not likely to get palytoxin poisoning just by having zoas or palythoa in your home aquarium. It resides in the flesh of the coral so it becomes an issue when the colony is damaged. People have gotten sick from scrubbing palythoa off of rocks or propagating a colony with a band saw that would send the particles airborne and then inhaled. People have also gotten sick by boiling rocks with colonies on it because that too sends the compounds airborne and unlike many other proteins, palytoxin does not lose its toxicity when heated.
