Care

Elegant Sand Divers are relatively hardy and can be a good choice for intermediate to advanced aquarists. They require a tank with a sandy substrate where they can burrow and hide. These fish are jumpers, so a well-fitted aquarium lid is essential to prevent escape. They thrive in a peaceful community and can be kept with other non-aggressive fish. A varied diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood will help maintain their health and coloration.

Reproduction

In the wild, Trichonotus elegans is known to spawn in pairs, with the female laying eggs in the sand which are then fertilized by the male. In the aquarium, breeding is not commonly reported, and specific details on their reproductive behavior in captivity are limited.

Habitat

Elegant Sand Divers are found in the Indo-Pacific region, from the Red Sea and East Africa to the western Pacific. They inhabit sandy areas near reefs and are often seen darting above the substrate or burrowing into it for protection. They typically reside at depths ranging from shallow waters to about 30 meters.
