Ventralis Anthias Female
Their gorgeous flowing fins no doubt inspired the Fairy reference and the Basslet portion of the name recognizes that they are the little cousins of Sea Basses and Groupers. Because of their small size, they do not pose a threat to other fish and make wonderful reef inhabitants. In the wild, Anthias form large schooling groups on the reefs. A single male will claim part of the reef as his and fight off other males that try to invade. The other Anthias present are juveniles and females, which the male keeps a watchful eye on. For aquariums, the females should be introduced first and a male at a later date.
One of the more difficult Anthias varieties to keep, the Ventralis Anthias, also known as the Longfin Anthias, does well in properly maintained reef tanks.

Added a group of female Ventralis Anthias to my 55-gallon reef tank. They are active and beautiful with their flowing fins. After a few weeks, I introduced a male, and they settled well. The tank remains stable and the fish are healthy.

The fish arrived quickly and looked healthy. I started with three females and waited two months before adding a male. They swim together in a school and don’t seem to stress each other. Good for a reef setup.

This is one of the most visually appealing anthias I’ve kept. The long fins are striking in the light. I maintain stable water conditions and they thrive. Only recommend for experienced reef keepers.
