Gobiodon histrio

Datasheet

General Description

The Broad-barred goby, also known as the Maori coral goby, is a small fish belonging to the Gobiidae family. This species, scientifically named Gobiodon histrio, can grow up to 4.0cm in size and is native to the Indo-West Pacific region, from the Red Sea to Samoa, and as far north as southern Japan and south to the Great Barrier Reef.

Aquarium Suitability

This goby species is suitable for aquariums with caution due to its docile nature, but it may display aggression towards similar species. It is advised to keep them in larger tanks, exceeding 50 liters, to cater to their needs effectively.

Demands, Care, and Hardiness

With average hardiness, the Broad-barred goby requires specific care during transportation and acclimation to aquarium conditions. It is a sensitive species that thrives best with Acropora corals, where they feel secure among the branches. Providing them with live feed enhances their adaptation to tank life.

Reef Suitability

Considered reef safe with caution, this goby species can be housed in a reef aquarium, especially with Acropora corals. However, care should be taken to ensure their interactions do not damage the corals.

Aquarium Setup

A suitable aquarium setup for Broad-barred gobies includes a tank size of at least 50 liters or more, with Acropora corals for them to hide among and potentially lay eggs. Maintaining a stable environment with appropriate water conditions, such as a pH of 8.1-8.4, a temperature range of 22.2-25.6°C, and a specific gravity of 1.020-1.025, is crucial for their well-being.

Behaviour

Broad-barred gobies are known to be very shy and docile, often seeking shelter among coral branches. They may exhibit aggression towards their own species and should be housed accordingly to prevent conflicts.

Feeding and Diet

These gobies have a varied diet, consuming small crustaceans like krill and mysis, zooplankton such as Cyclops and pods, and even small polyp stone corals. Supplying a diverse diet ensures their nutritional needs are met in captivity.

Dimorphism and Captive Reproduction

In captivity, it is possible to breed Broad-barred gobies, making them a potential option for aquarists seeking captive-bred specimens. The species may lay eggs on the underside of Acropora branches in pairs, requiring specific conditions for successful reproduction.

Habitat and Distribution

In the wild, these gobies inhabit regions spanning from the Red Sea to Samoa, favoring Acropora-rich environments in the Indo-West Pacific. Understanding their natural habitat helps replicate suitable conditions in aquarium settings for their well-being.
