Datasheet

General Description

The Pink-speckled shrimpgoby (Cryptocentrus leptocephalus), also known as the Singapore shrimp-goby, Singapore prawn-goby, or Pink-speckled shrimpgoby, belongs to the Gobiidae family, specifically the Cryptocentrus genus. These fish are small in size, typically growing up to 12.0cm, and are native to the Western Pacific region, ranging from Indonesia to New Caledonia and north to the Yaeyama Islands.

Aquarium Suitability

With a hardiness rating of "Hardy," the Pink-speckled shrimpgoby is suitable for aquarium keeping but requires careful consideration. It is recommended to house them in a tank of at least 100 liters, equipped with a substrate that allows for burrowing. Given their territorial nature, they can be aggressive towards similar species, making it essential to provide ample hiding spots and territory for each fish. Furthermore, they have a tendency to jump, so securing the tank is imperative.

Care and Hardiness

Caring for the Pink-speckled shrimpgoby involves frequent feeding multiple times a day, especially when first introduced to the tank. They thrive on a diet of small crustaceans like krill, mysis, and artemia. These fish prefer a sandy substrate with coral pieces and shells to dig burrows and establish territories. They have a symbiotic relationship with pistol shrimps of the Alpheus genus, aiding in maintaining burrows.

Reef Suitability

Pink-speckled shrimpgobies are deemed reef-safe, making them suitable for reef aquarium setups. Their small size and peaceful nature towards other reef inhabitants contribute to their compatibility with reef environments.

Aquarium Setup

In an aquarium setting, it is vital to mimic their natural habitat by providing a substrate that accommodates burrowing habits and the creation of territories. Using sand, coral pieces, shells, and rocks arranged securely can offer suitable conditions for these fish. Additionally, including pistol shrimps for symbiosis and ensuring minimal stress from other sand-dwelling species are crucial considerations.

Behaviour

These fish exhibit territorial behavior and can be aggressive towards fish encroaching on their space. Their symbiotic relationship with pistol shrimps highlights their cooperative nature in creating and maintaining burrows. Pink-speckled shrimpgobies may display jumping behavior, requiring caution in aquarium setups.

Feeding and Diet

Their diet primarily consists of small crustaceans, necessitating multiple feedings throughout the day to ensure their nutritional needs are met. Offering a variety of foods such as krill, mysis, and artemia helps maintain their health and vitality within the aquarium.

Dimorphism

Pink-speckled shrimpgobies may exhibit sexual dimorphism, with potential differences in coloration or size between males and females. In a captive environment, successful reproduction may be achieved; however, specific details regarding captive breeding are not provided.

Habitat and Distribution

Found in the waters of the Western Pacific, from Indonesia to New Caledonia and north to the Yaeyama Islands, the Pink-speckled shrimpgoby inhabits sandy substrates and shallow coastal areas. Their distribution also extends south to northwestern Australia and has recently been recorded in Tonga, showcasing their adaptability to various marine environments.
