Care

Henricia oculata is a hardy species that can adapt to life in a well-established aquarium. It requires a tank with plenty of live rock and a stable environment. This starfish is an omnivore and will scavenge for detritus, but it also benefits from supplemental feeding of finely chopped meaty foods and marine snow.

Reproduction

In the wild, Henricia oculata reproduces by releasing gametes into the water column, a process known as broadcast spawning. In the aquarium, however, reproduction is rare. Hobbyists interested in breeding should provide a large, mature system with excellent water quality to mimic natural conditions as closely as possible.

Habitat

The Blood Star is found in the cold waters of the North Atlantic, from the intertidal zone down to depths of around 200 meters. It prefers rocky substrates where it can find ample food sources and hide from predators.
