Pignose Puffer (Tetraodon suvattii)

Pignose Puffer (Tetraodon suvattii)

The Pignose Puffer, scientifically known as Tetraodon suvattii, is one of the most unique and fascinating freshwater puffers in the aquarium hobby. Also called the Arrowhead Puffer, this species stands out for its flat, triangular body, protruding snout, and powerful predatory behavior. Originating from the Mekong River Basin in Southeast Asia, the Pignose Puffer is a true ambush hunter, often burying itself in the substrate with only its eyes and snout exposed — waiting patiently for unsuspecting prey to pass by.

This species grows to about 6 inches (15 cm) and thrives in aquariums of at least 40–50 gallons, depending on the individual. It requires a fine sand substrate for burrowing, plenty of space for swimming, and strong filtration to handle its carnivorous diet. The water temperature should be kept between 75–82°F (24–28°C), with neutral to slightly alkaline pH. Because of its territorial and predatory instincts, the Pignose Puffer is best kept alone or in a single-species setup.

Feeding the Pignose Puffer can be a truly captivating experience. It is a dedicated carnivore that feeds on live or frozen prey such as fish, shrimp, worms, and crustaceans. Their powerful jaws and sharp beak are designed to crush shells, making snails and crayfish excellent choices to keep their teeth naturally trimmed. Due to their intelligence and awareness, they often learn to recognize their keepers and will respond to routine feeding times.

The Pignose Puffer’s exotic look and hunting behavior make it a prized specimen for advanced aquarists who enjoy keeping rare, behaviorally rich species. With proper care and a steady diet, this puffer can live for 8–10 years or longer, becoming one of the most memorable fish in a predator-focused aquarium.
