General Description
The Halfbarred goby (Amblygobius semicinctus) belongs to the Gobiidae family and is known for its small size, typically growing up to 11.0cm. This species is native to the Western Indian Ocean, specifically inhabiting areas in the East Indian Ocean and West Indian Ocean.
Aquarium Suitability
Considered suitable for aquariums, the Halfbarred goby is hardy and can thrive in a well-established tank with algae-covered rocks and stones. Despite their small size, they require a minimum tank size of 300 liters due to their habit of rearranging rocks and sand. The fish can live in pairs and is compatible with various other tank mates.
Demands, Care, and Hardiness
This species is hardy and mostly peaceful, although it may show aggression towards similar species. Halfbarred gobies thrive in water conditions with a pH of 8.1-8.4, a specific gravity of 1.020-1.025, a temperature range of 22.2-25.6°C, and a KH level of 8-12.
Reef Suitability
Known for being reef-safe, the Halfbarred goby is compatible with reef aquariums. However, it should be noted that these fish have a tendency to jump out of open aquariums, necessitating caution when setting up reef environments.
Aquarium Setup
To create an ideal habitat for the Halfbarred goby, it is crucial to provide a substrate that allows for burrowing. A mix of sand, coral pieces, shells, and broken-up shells can be ideal for them to dig holes in. Securely placed rocks assist in preventing toppling and aid in the fish creating a hole underneath for shelter.
Behaviour
This species is known to rearrange rocks and sand in the aquarium, emphasizing the need for stable décor. The Halfbarred goby may also occasionally eat flatworms and participate in aiding the maintenance of the substrate by filtering sand through its gills.
Feeding and Diet
In terms of diet, the Halfbarred goby feeds on microalgae such as spirulina, small crustaceans like krill and mysis, and zooplankton such as cyclops and pods. Supplementing their diet with algae-rich foods like spirulina is essential for their health.
Dimorphism
The Halfbarred goby exhibits multiple color variations, making identification sometimes challenging. Captive reproduction of this species has not been specifically discussed in the provided information.
