Care

Caring for Eschmeyer's Scorpionfish requires an advanced level of expertise. They need a well-established aquarium with plenty of live rock for hiding and hunting. The tank should be spacious enough to accommodate their territorial nature. These fish are not active swimmers, so the focus should be on providing ample structure rather than open swimming space. They feed on live or frozen meaty foods such as shrimp and small fish, and they may require live food initially to trigger their feeding response.

Reproduction

In the wild, Rhinopias species are solitary except during mating. Little is known about their breeding habits in home aquariums, as they rarely breed in captivity. However, they are oviparous, with females releasing eggs that are then fertilized by the male.

Habitat

Eschmeyer's Scorpionfish are found in the Indo-Pacific region, typically on coral reefs or rocky substrates where their camouflage is most effective. They are benthic and prefer to stay close to the bottom, often in areas with moderate to low current.
