Melichthys indicus: Triggerfish of the Indian Ocean

The Melichthys indicus, also known as the Indian Ocean triggerfish, is a marine fish with a sleek dark body featuring bluish or greenish hues. Its streamlined silhouette and powerful fins make it an excellent swimmer. Native to the coral reefs of the Indian Ocean, this fish is often spotted in open water, searching for food or mates.

This triggerfish is among the most resilient and adaptable species in marine aquariums. It is distinguished by its simple and elegant appearance, as well as its active but non-aggressive behavior in a well-designed tank.

A Fish Suitable for Large Volume Aquariums

To ensure the well-being of the Melichthys indicus, an aquarium of at least 500 to 600 liters is required. This fish enjoys long swimming areas and a few hiding spots among live rocks to rest or seek shelter in case of stress.

Although it is relatively peaceful, it can exhibit territorial dominance towards fish of similar shape or size. It is therefore advisable to keep it with robust species such as marine angels, other triggerfish, or butterflyfish.

Feeding the Melichthys indicus

The Melichthys indicus is an omnivore with a carnivorous tendency. It easily accepts:

• Pieces of shrimp, mussels, and squid
• Frozen krill and brine shrimp
• Pellets and flakes for carnivorous marine fish
• Occasional plant-based supplements of algae or Nori

It is recommended to feed it two to three times a day with a varied diet to maintain its full health and beautiful colors.

An Ideal Triggerfish for Experienced Aquarists

The Melichthys indicus is an excellent choice for enthusiasts of large but non-destructive marine fish. It is not compatible with invertebrates such as small crabs or snails, but it can be kept in a non-reef community aquarium with appropriate precautions.

This fish will add a touch of character to your aquarium while remaining more discreet than more aggressive triggerfish like the Balistoides or Pseudobalistes. Its constant swimming and resilience make it an ideal companion for a well-populated large volume aquarium.
