Liquidfins,
Thank you for your patience. The Wrought Iron Butterfly we currently have in the Aquaculture Coral & Marine Life Facility loves to pick at Zoanthus and Trachyphyllia, and would definitely not make a good candidate for a reef aquarium. Butterfly fish of the genus Chaetodon spp. are a risk when trying to introduce any of these fish to a reef aquarium. By nature these fish constantly pick at the substrate, rocks, and coral foraging all throughout the day.
