Common name: Salmacis Belli

General information

Salmacis belli, commonly known as Bell's Urchin, is a distinctive and attractive species of sea urchin found in the Indo-Pacific region. It is known for its striking appearance, with a combination of bright colors and unique banded patterns on its test (shell). This species is a part of the family Temnopleuridae and is appreciated by aquarists for its ornamental value in the reef aquarium.

Care

Bell's Urchin requires a well-established aquarium with plenty of live rock and a stable environment. It is important to maintain high water quality with stable parameters, as fluctuations can stress the urchin. They are generally peaceful and can coexist with a variety of tank mates. However, they may inadvertently damage corals or overturn small rocks while foraging for algae, so care should be taken when placing them in a reef tank.

Reproduction

In the wild, Salmacis belli reproduces by releasing gametes into the water column, where fertilization occurs externally. In the aquarium, breeding is less common, but with optimal conditions, it is possible to observe spawning behavior. The larvae are planktonic before settling and developing into juvenile urchins.

Symbiosis

While not known for any specific symbiotic relationships, sea urchins like Salmacis belli play a crucial role in the ecosystem by grazing on algae, which helps prevent overgrowth and maintain the balance of the reef.

Habitat

Salmacis belli is typically found in tropical coral reefs and rocky substrates, often at depths where light is sufficient for the growth of algae, which is their primary food source. They are distributed across the Indo-Pacific, from the Red Sea to the western Pacific Ocean.
