General information

The Kitefin Shrimp Goby, scientifically known as Paragobiodon lacunicolus, is a small and fascinating fish species that is well-suited for nano and pico reef aquariums due to its diminutive size. This species is part of the Gobiidae family, which is known for its diversity and the interesting behaviors of its members. The Kitefin Shrimp Goby is particularly noted for its symbiotic relationship with certain species of pistol shrimp.

Care

Kitefin Shrimp Gobies are relatively easy to care for but do require a stable and mature aquarium environment. They thrive in tanks with plenty of live rock and a sandy substrate that allows them to burrow and create shelters. These gobies are peaceful and can be kept with other non-aggressive tank mates. They are carnivorous and should be fed a varied diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood.

Reproduction

In the aquarium, Paragobiodon lacunicolus has been known to breed, with the male taking on the role of guarding the eggs. The eggs are typically laid in the burrows or on the ceiling of caves formed in the substrate. Successful breeding in captivity requires excellent water quality and a stress-free environment for the pair.

Symbiosis

One of the most intriguing aspects of the Kitefin Shrimp Goby is its symbiotic relationship with alpheid shrimp, commonly known as pistol shrimp. The shrimp and goby share a burrow, which the shrimp maintains while the goby stands guard. The goby benefits from the shrimp's digging efforts, while the shrimp relies on the goby's keen eyesight for warning against predators.

Habitat

Paragobiodon lacunicolus is found in the Western Pacific, from the Ryukyu Islands to Australia. It typically inhabits coral reefs and lagoons, often associating with branching corals like Acropora where it finds shelter and food. In the wild, they are usually observed at depths ranging from 1 to 25 meters.
