Amblygobius phalaena, commonly referred to as the White-barred Goby, is a popular choice for marine aquarium enthusiasts seeking a peaceful and active sand-sifting fish. This species is well-suited to reef tanks due to its generally calm temperament and reef-safe nature.
Care Level: Easy to moderate care makes this goby suitable for hobbyists with some marine aquarium experience. It thrives in stable water conditions and benefits from a well-established tank with a sandy substrate.
Temperament and Compatibility: Amblygobius phalaena is peaceful and non-aggressive, making it compatible with a wide range of community fish and invertebrates. It is best kept singly or in pairs unless housed in a very large aquarium to avoid territorial disputes.
Diet: This species is omnivorous, feeding primarily on small invertebrates and detritus sifted from the sand. Supplement its diet with high-quality frozen or live foods such as mysis shrimp, brine shrimp, and specialised sinking pellets to ensure optimal health.
Minimum Tank Size: A minimum of 75 litres (20 gallons) is recommended to provide adequate space for natural behaviour, particularly sand-sifting and territory establishment.
Lighting and Water Flow: Standard reef aquarium lighting is suitable. Moderate water flow mimics natural conditions and helps maintain water quality without stressing the fish.
Placement: Provide a sandy substrate with plenty of live rock for shelter and foraging. This species appreciates a well-structured environment with hiding spots and open sand patches for sifting.
Origin: Indo-Pacific region.
Maximum Size: Up to 12 cm (approximately 4.7 inches) in length.
