Amblyeleotris gymnocephala

Datasheet

• General DescriptionThe Masked Shrimpgoby (Amblyeleotris gymnocephala), also known as Mask Shrimpgoby or Nakedhead Shrimpgoby, belongs to the Gobiidae family, specifically Amblyeleotris. This species is categorized under Gobies, characterized as small bottom-dwelling fish that exhibit a range of behaviors in aquarium settings. Originating from the East Indian Ocean, Australia, Japan, New Zealand, and the Central/West Pacific regions, these fish can grow up to 14.0cm in size.

• Aquarium SuitabilityConsidered suitable for aquariums with proper care, the Masked Shrimpgoby requires a minimum tank size of 100 liters. They prefer substrates that allow for burrowing, such as sand, coral pieces, shells, and broken shell fragments, enabling them to create secure holes for shelter. These fish show hardiness in captivity but are known to be territorial and may exhibit aggression towards other fish approaching their territory. Thus, caution is advised when housing them with similar species.

• Care and HardinessBeing hardy in nature, the Masked Shrimpgoby necessitates frequent feeding, especially when newly introduced to the aquarium. Their diet should consist of small crustaceans like krill and mysis, as well as zooplankton such as Cyclops and pods. These fish thrive in water conditions with a pH range of 8.1-8.4, a specific gravity of 1.020-1.025, and a temperature range of 22.2-25.6°C (72-78°F).

• Reef SuitabilityThe Masked Shrimpgoby is reef-compatible and considered reef-safe, making it a suitable addition to reef aquariums. Their behavior in reef settings enhances the overall ecosystem dynamics without posing a threat to coral or other invertebrates.

• Aquarium SetupSetting up an aquarium for Masked Shrimpgobies involves providing ample space for burrowing activities. A substrate mix of sand, coral pieces, and shells should be arranged to facilitate hole creation. Additionally, ensuring secure rocks in the tank allows the fish to establish safe shelters. One must be cautious of other sand-dwelling creatures like Wrasses that may stress these gobies if the tank space is insufficient.

• BehaviourThese fish exhibit territorial behavior and may show aggression towards similar species or perceived intruders in their territory. Masked Shrimpgobies prefer having their own defined space within the aquarium and are known to interact closely with Pistol shrimps for symbiotic relationships, contributing to the dynamics of the tank environment.

• Feeding and DietThe diet of Masked Shrimpgobies consists of small crustaceans and zooplankton, which are essential components for their nutritional requirements. Regular feeding several times a day is recommended, especially in the absence of natural food sources in the aquarium. Providing a varied diet ensures the health and vitality of these fish in captivity.

• Habitat and DistributionIn their natural habitat, Masked Shrimpgobies are found in the waters of the Indo-West Pacific region. They are commonly sighted in areas such as the East Indian Ocean, Australia, Japan, New Zealand, and parts of the Central/West Pacific, where they thrive in sandy substrates and rocky environments, often forming symbiotic relationships with Pistol shrimps for mutual benefit.
