Canthigaster Compressa - The Compressed Toby

Canthigaster Compressa (The Compressed Toby)

Native to the Indo-Pacific, often found in coral reefs, seagrass beds, and rocky coastal areas.
Recognized by its elongated body, pointed snout, and intricate patterns covering its skin.
A small but bold species known for its inquisitive nature and unique swimming style.
Capable of inflating its body as a defense mechanism when threatened.
Requires a well-maintained tank with rock formations and open swimming areas for exploration.

Omnivorous, feeding on algae, small crustaceans, and invertebrates in the wild.
Accepts a variety of foods, including frozen shrimp, mysis shrimp, marine pellets, and algae-based diets.
Requires hard-shelled foods such as snails and clams to naturally wear down its continuously growing teeth.
Multiple small feedings per day help maintain health and energy levels.
A varied diet supports vibrant coloration and overall well-being.

Typically found in reef-associated habitats with sandy bottoms and coral rubble.
Prefers stable water conditions with moderate water flow.
Aquarium setups should include live rock formations, caves, and sandy substrate to encourage natural foraging.
Thrives in well-maintained marine tanks with an enriched environment.
Providing hiding spots and natural decor helps reduce stress and encourages natural behavior.

Optimal water temperature: 74-80°F (23-27°C) to support a strong 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 peaceful environment to prevent stress.
Providing an enriched habitat and a proper diet helps ensure 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 consume small invertebrates such as shrimp and crabs.
Should not be housed with overly aggressive fish that may cause stress.
Providing enough space and a structured environment minimizes territorial disputes.

A curious and active species that enjoys exploring its surroundings.
Frequently seen picking at rock surfaces and investigating objects in its environment.
Capable of inflating its body when startled, though this behavior should not be intentionally provoked.
Providing rock formations and varied tank decor encourages natural foraging behavior.
Over time, it can recognize its caretakers and display interactive behaviors during feeding.
