the ones to be extra careful of are the protopalys (the polyps that slime when touched) such as nuclear greens, purple deaths, button polyps, grandis and the like. Getting the slime into an open wound usually causes pain and sometimes infection.
But all zoanthids, whether zoanthus, palythoa or protopalythoa and probably including the yellow polyps should be handled with care, gloves and a face shield (polyps can squirt).
With careful handling, as should apply to all corals and many fishes, they pose little threat to you or the other inhabitants of a reef tank.
And no, they do not require any special equipment such as skimmers and the like except to keep the water parameters within the norms required by most all coral and S/W fish.
