General Description
The Masked Spinefoot, scientifically known as Siganus puellus, belongs to the Siganidae family. These fish are recognized for their efficacy in consuming algae, particularly bubble algae, making them a valuable addition to aquariums struggling with algae growth. With a maximum size reaching up to 38.0cm, they sport a distinctive appearance and have toxic spines on their backs as a defense mechanism.
Aquarium Suitability
Considered suitable for most aquarium setups, the Masked Spinefoot thrives in well-established tanks with ample algae growth for grazing. They require a minimum tank size of 2000 liters due to their swimming habits and can be challenging to keep well-fed if insufficient algae is present in the aquarium.
Demands, Care, and Hardiness
Masked Spinefoot are categorized as average in terms of hardiness, preferring water conditions with a pH range of 8.1-8.4, a temperature between 22.2-25.6°C, and a salinity range of 1.020-1.025. They are mostly peaceful but may exhibit aggression towards similar species, suggesting careful consideration when selecting tank mates.
Reef Suitability
Considered often reef safe, these fish can nibble on soft corals and LPS corals if food availability is insufficient. When well-fed, they contribute positively to reef ecosystems, showcasing their algae-consuming capabilities.
Aquarium Setup
Setting up an aquarium for Masked Spinefoot involves providing plenty of space for swimming and ensuring there is an adequate supply of algae for their diet. A well-established aquarium with algae-covered rocks and stones is essential, supplemented with plant-based flakes or Nori seaweed.
Behaviour
Masked Spinefoot are known to change color when frightened, often appearing pale or brownish. They can live as a pair, with a male and female cohabitating peacefully within the same environment.
Feeding and Diet
Their diet primarily consists of macroalgae like seaweed or Nori and microalgae such as Spirulina. While they have a diverse diet, maintaining an algae-based primary food source is crucial for their immune system and overall health.
Habitat and Distribution
These fish are native to the Indo-West Pacific region, specifically found from the Cocos-Keeling Islands to the Gilbert Islands, extending north to the Ryukyu Islands and south to the southern Great Barrier Reef and New Caledonia. Recently, they have also been recorded in Tonga, showcasing their widespread distribution within the marine environment.
