Common name: Spike-fin goby

General information

The Spikefin Goby, scientifically known as Discordipinna griessingeri, is a small and fascinating marine fish that is a gem for nano reef aquariums. This species is known for its distinctive dorsal fin that stands tall and is adorned with a series of spines, hence the common name. The body is typically a pale color with intricate, cryptic patterns that allow it to blend into its surroundings.

Due to their small size and peaceful nature, Spikefin Gobies are often sought after by aquarists who wish to add a touch of uniqueness to their tanks. They are not commonly found in the trade, which makes them a prized specimen for goby enthusiasts.

Care

Spikefin Gobies are suitable for small to medium-sized aquariums with plenty of live rock and a sandy substrate. They are bottom dwellers that appreciate a well-structured environment with hiding places. These gobies are generally hardy but can be sensitive to poor water quality, so maintaining pristine conditions is crucial.

Their diet should consist of small, meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood. Frequent, small feedings are recommended as they have a high metabolism.

Reproduction

In the wild, Spikefin Gobies are known to form monogamous pairs. The male prepares a nesting site, often under a rock or in a crevice, where the female will lay her eggs. The male then guards the eggs until they hatch. Reproduction in the home aquarium is rare but possible with the right conditions.

Habitat

Discordipinna griessingeri is found in the Western Pacific, particularly around the Philippines and Indonesia. They inhabit shallow reefs and lagoons, often hiding among rubble and coral fragments. In the aquarium, replicating this environment will provide them with the comfort they need to thrive.
