Common name: Tall-fin shrimp-goby

Care

Flagtail Shrimpgobies are bottom-dwelling fish that require a tank with a sandy substrate to mimic their natural habitat. They are known to burrow and create tunnels, so providing a fine sand bed is essential for their well-being. These gobies are not aggressive and can be kept with a variety of other peaceful fish and invertebrates. They thrive in a stable environment with good water quality and a diet that includes a variety of meaty foods such as frozen mysis shrimp, brine shrimp, and finely chopped seafood.

Reproduction

In the wild, Tomiyamichthys praealta is believed to form monogamous pairs and spawn within their burrows. However, breeding in captivity is rare, and little is known about their reproductive habits in home aquariums. Hobbyists interested in breeding these gobies should provide a stress-free environment with plenty of hiding places and a sandy substrate for burrow construction.

Symbiosis

One of the most fascinating aspects of the Flagtail Shrimpgoby is its symbiotic relationship with alpheid shrimps, also known as pistol shrimps. In this mutualistic association, the shrimp maintains and constructs a shared burrow while the goby stands guard, warning the shrimp of potential dangers with subtle body movements. This partnership allows both species to thrive, with the shrimp gaining protection and the goby benefiting from a well-maintained burrow.

Habitat

Tomiyamichthys praealta is found in the Western Pacific, particularly in sandy and rubble substrates near coral reefs. They are typically observed at depths ranging from 5 to 35 meters, where they inhabit burrows often shared with pistol shrimps.
