Canthigaster tyleri
Family: Tetraodontidae ยท Pufferfish
Also known as: Tyler's Toby, Tyler's Sharpnose Puffer, Tyleri Toby
The Tyler Toby is a small and rarely seen member of the Canthigaster genus, prized by collectors for its delicate beauty and scarcity in the aquarium trade. This diminutive pufferfish reaches only about 3 inches in length, making it one of the smallest puffers available to marine hobbyists. Its body features an attractive pattern of small dark spots scattered across a light tan to pinkish-brown base, with subtle blue lines and markings on the face that are characteristic of the Canthigaster genus. The overall impression is of a dainty, jewel-like pufferfish.
In the wild, Canthigaster tyleri is found in the Western Pacific, from Indonesia and the Philippines to Fiji and Tonga. It inhabits outer reef slopes and drop-offs at moderate depths, typically between 15 and 50 meters, which contributes to its rarity in the aquarium trade since collection at these depths is more challenging and expensive. It is found near coral rubble and small caves, where it picks at sponges, tunicates, and small invertebrates.
In the aquarium, the Tyler Toby is a peaceful and undemanding species when it can be obtained. Its tiny size allows it to thrive in tanks as small as 30 gallons, and it readily accepts frozen and prepared foods. Like other tobies, it is not considered reef-safe as it may nip at coral polyps and will eat small ornamental invertebrates. Its rarity and deep-water origin make it a coveted species among puffer enthusiasts, and specimens command premium prices when they appear in the trade.
Tyler Tobies are carnivores that feed on sponges, tunicates, and small invertebrates in the wild. In captivity, they readily accept frozen mysis shrimp, enriched brine shrimp, chopped clam, and quality marine pellets. Offer small hard-shelled foods occasionally for tooth maintenance. Feed two to three times daily in small portions due to their small stomach capacity.
The Tyler Toby is peaceful toward most tankmates but will consume small invertebrates and may nip at coral polyps. Its very small size makes it vulnerable to predation or bullying from larger, aggressive fish. Best kept with other small, peaceful species in a nano or small FOWLR setup. Avoid housing with large or aggressive tankmates that may intimidate or harm it.
Check CompatibilityTyler Tobies have not been bred in home aquariums. Like other Canthigaster species, they are likely substrate spawners with males providing nest guarding. The extreme rarity of this species in the trade makes obtaining breeding pairs impractical, and no documented captive breeding attempts exist.
