Common name: Needlespine coralgoby

General information

The Needle Goby, Gobiodon acicularis, is a small and slender fish known for its elongated body and vibrant coloration, which can range from bright green to yellow. This species is a member of the Gobiidae family and is often appreciated for its peaceful demeanor and interesting behavior. They are relatively rare in the aquarium trade compared to other gobies but can be a unique addition to a reef tank.

Care

Needle Gobies are suitable for small to medium-sized aquariums with plenty of live rock and hiding places. They are hardy and can adapt to a variety of tank conditions, but stable water quality is essential to prevent stress. These gobies are carnivorous and should be fed a diet of small meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood.

Reproduction

In the wild, Gobiodon acicularis forms monogamous pairs and spawns within the shelter of coral branches. In captivity, breeding can occur if a compatible pair is established. The male typically guards the eggs until they hatch.

Symbiosis

While not as well-known for symbiotic relationships as clownfish, some goby species, including the Needle Goby, have been observed forming mutualistic relationships with certain corals. They may seek refuge among the branches of stony corals, which provide protection from predators.

Habitat

Gobiodon acicularis is found in the Indo-Pacific region, particularly around coral reefs and lagoons. They prefer shallow waters where they can easily access coral shelters and feeding grounds.
