Care

Helen's Wrasse requires a well-established aquarium with plenty of live rock for hiding and hunting. They are peaceful fish that do well in a community tank but can be shy initially. It's important to provide a varied diet of small meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood to maintain their health and coloration. Care should be taken to ensure they do not compete with more aggressive feeders.

Reproduction

Little is known about the breeding habits of Plectranthias helenae in the wild or in captivity. However, like many wrasses, they are likely to be protogynous hermaphrodites, meaning they have the ability to change sex from female to male during their lifetime.

Habitat

Plectranthias helenae is found in the deep reefs and slopes of the Western Pacific, particularly around the Coral Sea and Great Barrier Reef. They tend to inhabit areas with moderate to strong currents and are often found at depths that are typically beyond the usual range for recreational scuba diving.
