Care
Paddlefin Shrimpgobies are relatively hardy and can adapt to life in an aquarium if provided with a sandy substrate for burrowing and hiding. They are peaceful fish that do well in a community tank with other non-aggressive species. It's important to cover the aquarium, as gobies can be skilled jumpers. They thrive on a varied diet of meaty foods, such as brine shrimp and mysis, and should be fed multiple times a day.
Reproduction
In the wild, Vanderhorstia dorsomacula is known to form monogamous pairs. While breeding in captivity is not common, providing a stress-free environment with plenty of hiding places can encourage natural behavior. The male typically guards the eggs until they hatch.
Symbiosis
Like many gobies, the Paddlefin Shrimpgoby may engage in a symbiotic relationship with burrowing shrimps. In this partnership, the shrimp digs and maintains a burrow that both the shrimp and the goby inhabit. The goby acts as a lookout, warning the shrimp of approaching predators. This fascinating behavior can sometimes be observed in the aquarium if both species are present.
Habitat
Vanderhorstia dorsomacula is found in the Indo-Pacific region, typically in sandy areas near coral reefs. They prefer shallow waters where they can easily dig and maintain their burrows.
