Acanthurus Triostegus (The Convict Tang)

Overview

• Native to the Indo-Pacific region, often found in shallow reef environments and lagoons.
• Recognized for its pale body with bold black vertical stripes, resembling a convict uniform.
• A peaceful schooling species known for its constant movement and algae-grazing behavior.
• Popular in marine aquariums due to its ability to control algae growth and social nature.

Feeding

• Herbivorous diet, primarily grazing on marine algae.
• Requires a diet rich in plant-based foods, including seaweed, spirulina, and high-quality herbivore pellets.
• Supplementing with fresh vegetables or dried seaweed supports optimal health.
• Frequent feedings encourage natural grazing behavior and sustain energy levels.

Habitat

• Commonly found in shallow coral reefs, lagoons, and rocky coastal areas.
• Prefers stable water conditions with moderate to strong water flow.
• Requires an aquarium with open swimming space and rock formations for grazing.
• Thrives in environments that mimic its natural surroundings with strong water movement.

Fish Care

• Optimal water temperature: 74-82°F (23-28°C).
• Ideal pH level: 8.1-8.4, with a specific gravity of 1.020-1.025.
• Hardy and disease-resistant but requires stable water conditions for long-term health.
• Best introduced into a mature aquarium with excellent filtration and strong water flow.
• Providing ample swimming space and hiding areas supports natural behaviors.

Compatibility

• Generally peaceful and can be kept in groups, unlike many other tang species.
• Compatible with a variety of reef-safe tank mates such as clownfish, wrasses, and angelfish.
• Should not be housed with overly aggressive species that may stress them.
• Does well in a community reef setup with proper space and hiding spots.

Aquarium Behavior

• Active swimmer, constantly moving and grazing on algae throughout the day.
• Generally non-aggressive but may become territorial in smaller aquariums.
• Often seen schooling in the wild and prefers the company of conspecifics in captivity.
• Providing an environment with live rock and algae supports natural behaviors.
