The Sharpnose Puffer is a small, striking, and highly active pufferfish, easily recognized by its elongated snout, bright white body, and vivid blue and yellow markings along the fins and tail. Known for its curious personality and playful behavior, it constantly explores its surroundings, making it a fascinating addition to reef and marine aquariums.

Sharpnose Puffers are omnivores that feed on small crustaceans, mollusks, and marine algae. In captivity, they accept a varied diet of mysis shrimp, brine shrimp, and algae-based foods. They are generally reef safe with caution, as they may nip at corals, clams, or other sessile invertebrates if underfed or stressed. Their unique behavior, bright coloration, and small size make them a popular choice for hobbyists seeking an active, eye-catching marine fish.
