In nature zoanthids are often found in turbid, high-nitrate areas in canals, harbors, intertidal areas and reefs.
For this reason they are fairly tolerant of poor water quality high nitrates, phosphates an dissolved organics.
They will not however do well if algae is allowed to grow as they can be smothered.

When it comes to placing zoanthids next to mushroom corals, the zoanthids almost always lose.
Always place these kinds of corals a good distance away from each other.
One should also be aware that there are several fish species that will dine on zoanthids.
These fish include the Raccoon Butterflyfish
