Euphyllia - This variety of Torch coral is sought after for its multiple colors. The tentacles are black and/or dark purple at the base and tipped with bright green. These specimens are cultured and not taken from the reef.
Give this stinging species plenty of space to grow away from other corals.
Torch corals need moderate lighting and water flow. It's necessary to maintain stable alkalinity, calcium, magnesium, and trace elements. Be sure to acclimate new coral to bright lighting slowly and carefully.
