Blacksaddle Toby
Canthigaster valentini
The blacksaddle toby is a small, venomless pufferfish found on Indo-Pacific coral reefs and lagoons. It commonly occurs in shallow tropical waters where it grazes on benthic invertebrates and algae, and it can inflate when threatened.

Identification points
- Small pufferfish with a dark saddle-like patch on the back behind the head
- Rounded body with a short snout and a tiny beak-like mouth
- Yellowish to brown body pattern with darker lines or blotches, typical of reef tobies
Habitat
Shallow coral reefs, reef flats, lagoons, and seaward reef slopes in tropical Indo-Pacific waters; often among coral heads and rubble in calm to moderately exposed areas.
Bait notes
Not a targeted game fish and usually of little angling value. If accidentally hooked, small baited hooks can take them; they may strike tiny pieces of shrimp or squid, but most anglers release them immediately.
Behavior
Day-active and inquisitive, picking at small crustaceans, worms, mollusks, and algae on the bottom. When stressed it swims in short bursts and can inflate like other puffers as a defense.
Caution
Contains tetrodotoxin and is unsafe to eat. Do not attempt consumption; also avoid handling too roughly because inflation and skin contact with body fluids can stress the fish.
Fishing notes
Rarely targeted; small reef fish gear or bait near coral and rubble may catch one incidentally. Handle minimally, keep away from tight tackle, and release promptly to reduce stress and injury.
