Canthigaster Amboinensis - The Ambon Puffer

Canthigaster Amboinensis (The Ambon Puffer)

Native to the Indo-Pacific region, commonly found in coral reefs, lagoons, and shallow rocky environments.
Recognized by its compact, oval-shaped body, yellowish-brown coloration, and distinctive blue lines around the face and body.
A curious and intelligent species known for its bold personality and unique swimming behavior.
Possesses the ability to inflate its body as a defense mechanism when threatened.
Requires a well-maintained aquarium with ample swimming space and rock formations for hiding and foraging.

Omnivorous, primarily feeding on algae, small crustaceans, and invertebrates in the wild.
Readily accepts frozen shrimp, mysis shrimp, marine pellets, and chopped seafood.
Requires hard-shelled foods such as snails or clams to help wear down continuously growing teeth.
Multiple small feedings per day are recommended to meet its dietary needs.
A well-balanced diet supports vibrant coloration and overall health.

Typically found in reef-associated environments with sandy bottoms and coral rubble.
Prefers stable water conditions with moderate water movement.
Aquarium setups should include live rock formations, caves, and sandy substrate for natural foraging.
Thrives in well-maintained marine tanks with a diverse environment.
Providing a structured habitat with various hiding places helps reduce stress and encourages natural behavior.

Optimal water temperature: 74-80°F (23-27°C) to support a healthy immune system.
Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
Requires efficient filtration and regular water changes to maintain water quality.
Avoids aggressive tank mates, as it can become stressed in a high-aggression environment.
Providing a well-balanced diet and enriched habitat promotes a long, healthy life.

Generally peaceful but may nip at the fins of slow-moving fish.
Compatible with tangs, wrasses, and other semi-aggressive fish.
Not safe with small invertebrates such as shrimp and crabs, as they may be seen as prey.
Should not be housed with overly aggressive fish that could intimidate or outcompete it for food.
Providing enough space and a well-structured environment helps minimize territorial disputes.

A highly curious species that enjoys exploring its environment.
Often observed picking at rock surfaces and searching for small prey.
Capable of inflating its body when startled or threatened, although this behavior should not be intentionally provoked.
Providing rock formations and natural decor encourages active foraging and reduces boredom.
Over time, it can become highly interactive with caretakers and recognize feeding routines.
