Fusigobius signipinnis

Datasheet

General Description
The Signalfin goby, scientifically known as Fusigobius signipinnis, is a small fish belonging to the Gobiidae family, known for their tendency to live close to the bottom of the ocean. They are typically found in the Western Pacific region, ranging from Japan to Australia, with recent sightings in Tonga.

Aquarium Suitability
Considered suitable for aquariums with care, the Signalfin goby thrives better when housed without other members of the same species. They are docile and shy, requiring good hiding spots like between live rocks to feel secure.

Demands, Care, and Hardiness
With an average hardiness level, these gobies assist in maintaining the cleanliness of the sandy substrate by filtering out food particles. They are known to be less proficient at sand filtering compared to other similar species and need frequent feeding, especially when newly introduced to an aquarium.

Reef Suitability
Always reef safe, Signalfin gobies are compatible with reef environments and make a great addition to reef tanks without causing harm to coral or other inhabitants.

Aquarium Setup
To set up an aquarium for the Signalfin goby, it is recommended to provide a minimum tank size of 100 liters with appropriate hiding places and a substrate that allows for their natural behavior. Maintaining water conditions within the parameters of a pH range of 8.1-8.4, a specific gravity of 1.020-1.025, a temperature range of 22.2-25.6°C, and a carbonate hardness (KH) of 8-12 is crucial for their well-being.

Behaviour
The Signalfin goby species may exhibit aggression towards similar species, so it's important to monitor their behavior, especially in a tank with multiple gobies. They are known for their shy and docile nature, making them a peaceful addition to community aquariums.

Feeding and Diet
Signalfin gobies predominantly feed on small crustaceans such as krill, mysis, and artemia. In addition, they also consume zooplankton like cyclops and pods, making their diet diverse and vital for their overall health.

Dimorphism
In terms of dimorphism, male and female Signalfin gobies may exhibit differences in coloration or size, but further details on captive reproduction of this species are not provided.

Habitat and Distribution
Native to the Western Pacific, Signalfin gobies are commonly found in regions stretching from Japan to Australia, with recent sightings also reported in Tonga. They prefer sandy substrates in their natural habitat and are often seen close to the ocean floor.
