General Description
The Siganus spinus, commonly known as the Scribbled spinefoot or Little spinefoot, belongs to the Siganidae family. These rabbitfish are recognized for their effectiveness in consuming algae, especially bubble algae, making them valuable for algae control in aquariums.
Aquarium Suitability
Considered suitable for most aquariums, Siganus spinus requires a well-established tank with ample space for swimming. Due to their toxic spines, caution is advised when handling them. These fish tend to hide when feeling threatened, displaying color and pattern changes as a form of camouflage.
Demands, Care, and Hardiness
With an average hardiness level, the Little spinefoot thrives in water conditions with a pH ranging from 8.1 to 8.4, a temperature between 22.2-25.6°C, and a specific gravity of 1.020-1.025. They require a diet primarily based on algae to maintain good health and well-being.
Reef Suitability
When well-fed, Siganus spinus can be considered reef-safe; however, inadequate food availability may lead to them nibbling on soft coral and LPS. Their presence in a reef tank contributes to algae management but should be monitored for any signs of coral nipping.
Aquarium Setup
For optimal care, the aquarium housing Little spinefoot should contain algae-rich rocks and stones for grazing. It is essential to have a well-maintained tank where these fish can fulfill their natural grazing behavior. Supplementing their diet with macroalgae like seaweed and microalgae such as spirulina is recommended.
Behaviour
Typically peaceful, Siganus spinus may exhibit aggression towards similar species. They tend to form pairs, consisting of a male and a female. When frightened, these fish can change color, often becoming pale or brownish as a defense mechanism.
Feeding and Diet
Little spinefoot are efficient algae eaters, consuming significant amounts of algae from rocks, including green hair algae and filamentous algae. While they enjoy a variety of frozen foods, maintaining an algae-based diet is crucial for their immune system health.
Habitat and Distribution
In the wild, Siganus spinus is found in the Indo-West Pacific region, spanning from India to French Polynesia, with their range extending from Japan to New Caledonia. It's important to note that these fish require sufficient space for swimming and grazing in their natural habitat.
