General Description
The Spotted Surgeonfish, scientifically known as Ctenochaetus strigosus, belongs to the Acanthuridae family. This species is characterized by its specialized teeth that allow them to feed on algae and other organic material by scraping them from rocks and stones. They are generally peaceful and less active compared to other surgeonfish species, making them suitable for smaller aquariums.
Aquarium Suitability
The Spotted Surgeonfish is considered suitable for aquariums with proper care. They are not recommended to be housed with more aggressive surgeonfish species due to their mild behavior. It is advised to provide ample sand and rocks in the tank for them to exhibit their natural behavior effectively. This fish requires hiding places, especially when newly introduced into the aquarium.
Demands, Care, and Hardiness
Ctenochaetus strigosus is classified as delicate in terms of hardiness. They thrive in well-established aquariums with plenty of space for swimming. It is crucial to maintain a tank with algae-rich rocks and stones as their primary food source to support their immune system's health. Regular feeding of plant-based fish flakes, Nori seaweed, or similar is recommended.
Reef Suitability
The Spotted Surgeonfish is consistently reef-safe and rarely causes irritation to corals or invertebrates. They spend their time swimming around and nibbling algae from stones, contributing to keeping the aquarium free of unwanted algae growth. However, larger Palettes/Blue tangs may occasionally display aggressive behavior towards other tank mates.
Aquarium Setup
For optimal care of the Spotted Surgeonfish, a well-run aquarium is essential where they can graze on algae from rocks and stones. Adequate space for swimming should be provided, and it is crucial to ensure a well-maintained environment with suitable water conditions. This species thrives in a tank with a recommended minimum size of 400 liters.
Behaviour
Ctenochaetus strigosus exhibits mostly peaceful behavior but can display aggression towards similar species if not introduced in the correct order. When housed with multiple surgeonfish species, establishing a hierarchy is common. Providing hiding spots and individual sleeping areas can reduce stress and potential conflicts among tank mates.
Feeding and Diet
The diet of the Spotted Surgeonfish primarily consists of macroalgae like seaweed or Nori and microalgae such as Spirulina. While they enjoy a variety of frozen foods, maintaining an algae-based diet is crucial for their overall health and well-being. Supplementing their diet with algae-rich foods ensures their nutritional requirements are met.
Dimorphism
The Spotted Surgeonfish does not display significant dimorphism. However, it is crucial to note that some individuals of this species may find it challenging to acclimatize to aquarium conditions. Captive reproduction of these fish, if covered, depends on specific breeding strategies and environmental factors in a controlled setting.
Habitat and Distribution
Endemic to the Hawaiian Islands and Johnston Island in the Eastern Central Pacific, the Spotted Surgeonfish is also found in Australia in the Western Central Pacific region. They inhabit areas with ample sand and rocks, where they can graze on algae and organic material. Their distribution highlights their affinity for tropical marine environments conducive to their feeding habits.
