Canthigaster valentini
Family: Tetraodontidae ยท Pufferfish
Also known as: Saddled Toby, Black Saddled Toby, Valentini Sharpnose Puffer
The Valentini Puffer, also known as the Saddled Toby, is a small and charismatic pufferfish that has become enormously popular in the marine aquarium hobby. Its compact body displays a distinctive pattern of dark brown to black saddle markings over a white to cream base, accented with orange-brown spots on the lower body and blue-green line markings on the face. Like all pufferfish, it can inflate its body when stressed or threatened.
This species is one of the smaller pufferfish available, making it suitable for moderately sized aquariums. It is intelligent, curious, and quickly develops a personable relationship with its keeper, often begging for food at the glass. The Valentini Puffer is hardy and readily accepts a wide variety of foods, including frozen and prepared offerings.
Despite its charm, the Valentini Puffer is not reef-safe and will nip at corals, clam mantles, fan worms, and various invertebrates. Its beak-like fused teeth are designed for crushing hard-shelled prey, and it should be offered hard foods regularly to prevent overgrowth. Best suited for fish-only setups or very carefully managed reef tanks where the owner accepts some risk. It can be semi-aggressive toward slow-moving or long-finned tankmates.
Valentini Puffers are omnivores that feed on algae, tunicates, coral polyps, and small invertebrates in the wild. In captivity, offer a varied diet of frozen mysis shrimp, krill, chopped clam, squid, marine pellets, and algae. Provide hard-shelled foods like snails or clams regularly to wear down their continuously growing teeth. Feed two to three times daily.
The Valentini Puffer can nip at corals, clams, fan worms, and the fins of slow-moving or long-finned fish. It is best kept in fish-only setups with moderately active tankmates. Avoid housing with seahorses, pipefish, or slow-moving species. Generally peaceful toward robust, active fish of similar size.
Check CompatibilityValentini Puffers have been bred in captivity on a limited basis. Males court females and eggs are deposited on substrate. The male may guard the nest. Larvae are very small and require specialized planktonic foods. Captive breeding remains uncommon in the hobby.
