I’ve kept this anthias for six months in a 75-gallon tank with live rock and corals. It’s active but calm, and hasn’t shown any aggression. Feeding is straightforward with high-quality marine flakes and frozen foods. Only recommend for experienced reef keepers.

The fish arrived healthy and has been thriving in my 70-gallon tank. It’s a beautiful addition to the reef, and its coloration is vibrant. I do need to monitor water parameters closely, which is a bit demanding.
