Common name: Triangular Pygmy Goby

General information

The Triangular Pygmy Goby, scientifically known as Paraclavarina triangularis, is a small and fascinating marine fish species. It is part of the Gobiidae family, which is one of the largest families of marine fishes. This species is known for its triangular-shaped head and its diminutive size, rarely exceeding a few centimeters in length. The coloration of P. triangularis is typically a mottled pattern of browns and whites, allowing it to blend seamlessly with its surroundings.

Care

Due to their small size, Triangular Pygmy Gobies can be kept in nano or pico reef aquariums. They require a well-established tank with plenty of live rock and hiding places to feel secure. These gobies are peaceful and can be kept with other non-aggressive tank mates. They are carnivorous, feeding on small invertebrates and zooplankton in the aquarium. Care should be taken to ensure they are not outcompeted for food by larger, more aggressive fish.

Reproduction

Like many gobies, P. triangularis may form monogamous pairs and spawn within the aquarium. They typically lay their eggs in a sheltered location, such as under a rock or in a crevice. The male is known to guard the eggs until they hatch. Breeding these gobies in captivity can be a rewarding experience for the dedicated hobbyist.

Habitat

Paraclavarina triangularis is found in the Indo-Pacific region, often inhabiting shallow reefs and lagoons. They prefer areas with sandy substrates and coral rubble where they can easily camouflage and search for food. Their natural habitat includes a range of microhabitats, which should be replicated in the home aquarium to provide a sense of security and natural behavior.
