General Description
The Monster Shrimpgoby (Tomiyamichthys oni) belongs to the Gobiidae family known for their small size and bottom-dwelling nature. These fish are generally hardy and well-suited for aquarium life. They exhibit shy and docile behavior, making them a peaceful addition to a tank environment. With a maximum size of 11.0cm, they require a substrate that allows for burrowing, preferably comprising sand, coral pieces, shells, and broken shell fragments.
Aquarium Suitability
Considered suitable for aquariums with proper care, the Monster Shrimpgoby can coexist as a pair if introduced simultaneously. Due to their docile nature, caution is advised when housing them with more aggressive tank mates. With a minimum tank size of 50 liters, these fish prefer a spacious environment where they can establish a burrow at least 1.5 inches longer than their body length.
Demands, Care, and Hardiness
The Monster Shrimpgoby is characterized as average in hardiness, requiring multiple feedings per day, especially upon introduction to a new tank. They are initially shy but can adapt to tank life over time. These fish thrive when provided with a suitable diet of small crustaceans, zooplankton, and other live foods.
Reef Suitability
Reef enthusiasts can enjoy adding the Monster Shrimpgoby to their setups as they are always considered reef safe. Their peaceful temperament makes them a compatible choice for reef tanks, provided they are not housed with similar species that may provoke aggression.
Aquarium Setup
When setting up an aquarium for the Monster Shrimpgoby, it is crucial to create a substrate that allows burrowing and hole-digging. Incorporating rocks to facilitate hole creation and ensure stability is recommended. Avoid overcrowding the tank with other burrowing species to prevent stress on the Shrimpgoby.
Behaviour
These Gobies exhibit mostly peaceful behavior but may display aggression towards similar species. They are known to be symbiotic with Pistol shrimp of the genus Alpheus, forming a cooperative relationship where the shrimp maintains the burrow while the Goby acts as a lookout.
Feeding and Diet
Feeding the Monster Shrimpgoby a varied diet consisting of small crustaceans like krill, mysis, and artemia, along with zooplankton such as Cyclops and live pods, is crucial for their health and well-being in captivity.
Habitat and Distribution
Found in regions like Australia, Japan, and the Central/West Pacific, the Monster Shrimpgoby inhabits sandy bottoms and rocky reefs where it can burrow and establish its territory. This species thrives in environments that mimic their natural habitat, emphasizing the need for a suitable substrate in aquarium settings.
