Zoanthids Coral Frag - Almost WYSIWYG (Zoanthus sp.)

Zoanthus coral frags are relatively easy to care for, making them great choices for beginner and seasoned aquarists alike. They thrive in low to moderate water flow and under moderate lighting provided by T-5s, powerful LEDs, or metal halides. Regular supplementation of iodine and trace elements will help maintain polyp health and coloration.

These corals multiply easily in established reef systems through budding, expanding their colony coverage over time. The symbiotic zooxanthellae algae they host fulfill most of their nutritional needs through photosynthesis. However, under suboptimal lighting, they may benefit from supplemental feeding with micro-plankton, baby brine shrimp, or other filter-feeder foods.

Note that Zoanthus corals can exhibit semi-aggressive behavior by extending short sweeper tentacles, so provide ample space between colonies and neighboring corals to reduce crowding or stinging.

It's common to receive frags or rocks not fully covered in polyps, but under stable conditions, these corals will quickly spread, eventually covering both the base rock and surrounding surfaces with a colorful, living mat.
