Canthigaster Coronata - The Crowned Toby

Canthigaster Coronata# (The Crowned Toby)

Native to the Indo-Pacific, commonly found in coral reefs, rocky ledges, and coastal lagoons.
Distinguished by its compact body, subtle brownish coloration, and faint, wavy blue lines on its face.
A small but confident species known for its curious and bold nature.
Has the ability to inflate its body as a defense mechanism when threatened.
Requires a well-maintained tank with plenty of hiding spots and open swimming areas.

Omnivorous, primarily consuming algae, small crustaceans, and invertebrates in the wild.
Accepts a variety of foods, including frozen shrimp, mysis shrimp, marine pellets, and chopped seafood.
Requires hard-shelled foods such as snails or clams to help naturally grind down its continuously growing teeth.
Multiple small feedings per day ensure optimal health and prevent malnutrition.
A varied diet supports strong coloration and overall vitality.

Typically found in shallow reefs and rocky outcrops with sandy or rubble substrates.
Prefers stable water conditions with moderate water movement.
Aquarium setups should include live rock structures, caves, and sandy substrate for natural foraging.
Thrives in well-maintained marine tanks with a balanced environment.
Providing hiding places and natural decor helps reduce stress and encourages natural behaviors.

Optimal water temperature: 74-80°F (23-27°C) to maintain 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.
Should be kept in a low-stress environment to thrive.
Providing an enriched habitat and a varied diet supports longevity and overall well-being.

Generally peaceful but may nip at slow-moving fish with long fins.
Compatible with tangs, wrasses, and other semi-aggressive fish.
Not reef-safe, as it may prey on small invertebrates such as shrimp and crabs.
Should not be housed with overly aggressive fish that may cause stress or compete for food.
Providing enough space and a structured environment minimizes territorial behavior.

A curious and observant species that actively explores its surroundings.
Often seen picking at rock surfaces and searching for small prey.
Capable of inflating its body when startled, though this behavior should not be intentionally triggered.
Providing rock formations and varied tank decor promotes natural foraging behavior.
Over time, it can become interactive with caretakers and recognize feeding routines.
