Common name: Pale spine fire urchin

General information

The Blue-Spotted Sea Urchin, scientifically known as Astropyga magnifica, is a visually striking invertebrate that is popular among reef aquarium enthusiasts. This species is known for its vibrant blue spots and long, dark spines that can add a dramatic flair to any marine setup. It is important to note that while they are beautiful, their spines are sharp and can inflict a painful sting if handled carelessly.

Care

Care for Astropyga magnifica requires a well-established aquarium with plenty of live rock and a sandy substrate where they can forage for algae and detritus. They are generally hardy but should be kept in a tank with stable water conditions and moderate to strong water flow to mimic their natural habitat. It's crucial to provide them with enough space to move around without damaging themselves or other tank inhabitants.

Reproduction

In the wild, Astropyga magnifica reproduces by releasing gametes into the water column in a process known as broadcast spawning. In the aquarium, breeding is less common, but hobbyists can encourage reproduction by maintaining excellent water quality and simulating natural seasonal changes in lighting and temperature.

Symbiosis

While not known for any specific symbiotic relationships, Astropyga magnifica plays a role in the ecosystem by consuming algae and helping to keep the reef clean. They can coexist with a variety of tank mates as long as they are not small enough to be accidentally harmed by the urchin's spines.

Habitat

The Blue-Spotted Sea Urchin is typically found in the Indo-Pacific region, from the Red Sea to the Western Pacific. They inhabit coral reefs and rocky substrates, often at depths ranging from shallow waters to about 40 meters deep. In the aquarium, replicating this environment will help ensure their well-being.
