As aquarium fish
This species is nocturnal and therefore the most active when the light is dimmed or turned off.
This species can eat large amounts of algae (relative to their size) from rocks, like green hair algae and filamentous algae.
As it doesn’t eat every algae type, in case of a specific algae plague, find out more precise information.
This species needs good hiding places, for example, between live rocks.
Family description (Echinoidea)
Sea urchins are often used to keep various algae at bay.
They are very effective algae eaters, and will eat anything from coralline algae to green hair algae.
Sea urchins must not be kept in an aquarium with few algae, as they may starve to death.
Sea urchins should be acclimatized slowly, due to sensitivity towards changes in salinity.
