General Description
The Orangelined Triggerfish, scientifically known as Balistapus undulatus, belongs to the family Balistidae. These fish are characterized by their strong jaws used for crushing rock, shells, or corals while hunting for food. They exhibit significant variability in behavior, not just between species but even among individual specimens.
Aquarium Suitability
Considered suitable with caution, due to their aggressive nature, Orangelined Triggerfish can pose a threat to smaller and more peaceful fish in the tank. Their diet may include shrimps, crabs, small bivalves, snails, and they are known to bite at times. They require a varied diet to maintain their health and should be provided with ample space and hiding spots to help alleviate aggressive tendencies.
Care and Hardiness
Known for their hardy nature, these fish require a tank of at least 2000 liters to thrive. They need regular feeding, hiding places among live rocks, and a varied diet to prevent their teeth from overgrowing, which might require stressful grinding procedures to correct. During transportation and acclimatization into an aquarium, they are particularly sensitive.
Reef Suitability
Orangelined Triggerfish are not considered reef-safe due to their tendency to rearrange rocks and substrate. They are likely to prey on crustaceans and other invertebrates commonly found in reef environments.
Aquarium Setup
Setting up an aquarium for Orangelined Triggerfish involves securing rocks in place to prevent them from toppling over as the fish rearrange their environment. Providing ample space for swimming and hiding places, such as among live rocks, is crucial for their well-being.
Behaviour
These triggerfish are known for their playful and interesting personalities, with some owners even teaching them tricks using food as incentives. They may exhibit behaviors like swirling sand to uncover food and spraying water from the surface, posing a risk to electrical equipment.
Feeding and Diet
Their diet should consist of various foods such as fish, larger crustaceans, small crustaceans like krill and mysis, and other invertebrates. Offering a diverse diet is essential to keep them healthy.
Habitat and Distribution
Orangelined Triggerfish are found in the Indo-Pacific region, ranging from the Red Sea to Natal, South Africa, and east to various islands in the Pacific. They prefer habitats with ample hiding spots and space for swimming in rocky and coral-rich areas.
