Care

Fourmanoir's Shrimpgoby requires a well-established aquarium with a sandy substrate to mimic its natural environment. The tank should also have ample hiding places and a peaceful community. They are not aggressive and can be kept with other non-predatory fish. A varied diet of meaty foods and high-quality prepared foods will keep them healthy and vibrant.

Reproduction

In the aquarium, breeding Fourmanoir's Shrimpgoby can be a rewarding experience. They are cave spawners, laying their eggs in burrows or crevices. The male typically guards the eggs until they hatch. Breeding success increases in a stress-free environment with excellent water quality.

Symbiosis

One of the most interesting aspects of Fourmanoir's Shrimpgoby is its symbiotic relationship with alpheid shrimps. In the wild, these gobies share burrows with shrimps, maintaining a lookout for predators while the shrimp digs and maintains the burrow. This mutualistic relationship can also be observed in the home aquarium if both species are kept together.

Habitat

Tomiyamichthys fourmanoiri is found in the Western Pacific, from the Philippines to northern Australia. They inhabit sandy and rubble substrates in coastal reefs and lagoons, often at depths where light is still sufficient for coral growth.
