Canthigaster bennetti
Family: Tetraodontidae ยท Pufferfish
Also known as: Bennett's Sharpnose Puffer, Bennett's Toby, Exquisite Toby
The Bennett Toby is a small and attractive sharpnose puffer found throughout the western Pacific, where it inhabits coral reefs and lagoons at moderate depths. Its compact body displays an intricate pattern of brown and tan markings with blue-green lines radiating from the eyes and scattered across the face, giving it an ornate and distinctive appearance. Like all Canthigaster species, it possesses a small, pointed snout and fused beak-like teeth designed for crushing hard-shelled prey.
In the wild, Bennett's Toby maintains a small territory on the reef, feeding on a variety of small invertebrates, algae, and detritus. Males are territorial and typically maintain harems of several females. This social structure means that in captivity, only one specimen should be kept per tank unless the system is large enough to support a male-female pair.
The Bennett Toby is considered one of the easier toby puffers to maintain in captivity. Its small adult size of around 4 inches makes it suitable for moderately sized aquariums starting at 30 gallons. It is hardy, adapts readily to prepared foods, and develops an engaging, interactive personality. However, like all puffers, it is not reef-safe and will readily consume small invertebrates, nip at coral polyps, and investigate sessile organisms with its powerful beak.
Bennett Tobies are carnivores that primarily feed on small invertebrates, tunicates, sponges, and algae in the wild. In captivity, offer a varied diet of frozen mysis shrimp, brine shrimp, chopped krill, and high-quality marine pellets. Provide hard-shelled foods such as small snails occasionally to wear down their continuously growing beak-like teeth. Feed two to three times daily.
The Bennett Toby is generally peaceful toward other fish but will consume small invertebrates and may nip at coral polyps, clam mantles, and tube worms. Best kept in fish-only setups with similarly sized, active tankmates. Avoid housing with seahorses, pipefish, or delicate invertebrates. Keep only one per tank unless maintaining a male-female pair.
Check CompatibilityBennett Tobies are harem spawners in the wild, with dominant males maintaining territories containing multiple females. Eggs are deposited on substrate and may receive some parental guarding. Captive breeding is rarely documented and larvae require specialized planktonic foods.
