how to care for zooanthids..

Not to put you off these beautifull corals, but if you plan on filling your tank with these things, you may want to google search, zoa's contain the 2nd most lethal toxin in the world, and great care should be sought when handleing these, especially when fragging, goggles and gloves should be worn, just a heads up.

Good luck...

 

Palythoas contain the highest level of toxin(palytoxin).
Different zoanthids require different lighting and water flow requirements. It is best to experiment with the placement in your tank. Moreover, as mentioned, these polyps can and will eventually spread over time! Because of this you have to pay attention to the placement of other neighboring corals as zoanthids can grow, possibly kill and take over other corals if allowed. Either by reducing light, water flow or their chemical makeup, you should try to contain the zoanthids and keep them away from stony corals!
