General Description
The Spider-eye puffer, scientifically known as Canthigaster amboinensis, is a species from the Canthigaster genus, belonging to the Tetraodontidae family. These smaller pufferfish lack the ability to inflate themselves as dramatically as some larger species. Known for their unique swimming behavior, interesting personalities, and occasional tendency to nip at other fish and invertebrates, these fish are native to the Indo-Pacific region.
Aquarium Suitability
The Spider-eye puffer is considered suitable for aquariums with proper care. They are mostly peaceful but can exhibit aggression towards similar species of the same gender. This species is not reef-safe due to its potential to harm invertebrates like shrimp, crabs, and soft coral. Aquarists need to be cautious as these fish have toxic skin, releasing a poison when highly stressed or dying, which can be harmful to other aquatic life in the tank.
Demands, Care and Hardiness
Having an average level of hardiness, Spider-eye puffers require a well-established aquarium with algae where they can graze. They need a diet that helps prevent their teeth from overgrowing, consisting of macroalgae, microalgae, and small crustaceans. Tank conditions should have a pH 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 of 8-12°dKH.
Reef Suitability
The Spider-eye puffer is not considered reef-compatible due to its tendency to nip at corals and other reef inhabitants. They feed on larger crustaceans, invertebrates, and soft corals, posing a threat to the delicate balance of a reef tank.
Aquarium Setup
Aquarium setup for Spider-eye puffers should include a tank size of at least 500 liters, ample algae growth for grazing, and careful consideration of tank mates to avoid aggression. It's essential to avoid stressing the fish during handling and transportation to prevent the release of toxins from their skin.
Behaviour
Spider-eye puffers are known for their fun and interesting personalities. While mostly peaceful, they may exhibit aggression towards similar species of the same gender. These fish are active swimmers and need ample space to move around in the tank.
Feeding and Diet
The diet of Spider-eye puffers should consist of foods that help prevent teeth overgrowth, such as macroalgae, microalgae, and small crustaceans. A varied selection of seafood and frozen foods is essential for their nutritional needs.
Dimorphism
Spider-eye puffers can live as a pair, with male and female specimens cohabitating peacefully. These fish may exhibit slight differences in size or color between genders.
Habitat and Distribution
Spider-eye puffers are found in the Indo-Pacific region, ranging from East Africa to the Galapagos Islands, north to southern Japan and Hawaii, and south to the Great Barrier Reef and the Society Islands. These fish inhabit coral reefs and coastal areas with abundant invertebrate populations for feeding.
