HAIRY PUFFER (Pao baileyi) (Formerly Tetraodon baileyi)*

Own One of the World’s Rarest Freshwater Puffer Fish

The Hairy Puffer (Pao baileyi), formerly known as Tetraodon baileyi, is one of the rarest and most fascinating freshwater puffers available in the aquarium hobby. Famous for the small dermal appendages that give it a “hairy” appearance, this remarkable species is a true centerpiece for experienced aquarists who appreciate unusual and highly intelligent predatory fish.

Native to the Mekong River Basin in Thailand and Laos, the Hairy Puffer inhabits slow-moving rivers and flooded forest habitats where it uses exceptional camouflage to ambush prey. Its mottled brown coloration, textured skin, and unique body shape allow it to blend seamlessly into driftwood and leaf litter. Unlike many freshwater fish, the Hairy Puffer often remains motionless while waiting for food before launching a rapid attack.

Monster Aquarium Canada proudly offers healthy Hairy Puffers with professional live fish shipping across Canada. Every specimen is carefully selected, quarantined when appropriate, and professionally packed to help ensure safe arrival.

Diet

Hairy Puffers require a varied carnivorous diet consisting of snails, mussels, clams, shrimp, earthworms, bloodworms, and other meaty frozen or live foods. Hard-shelled foods are particularly important because they help naturally wear down the puffer’s continuously growing teeth.

A varied diet supports healthy growth, vibrant coloration, and long-term dental health.

Compatible Tank Mates

The Hairy Puffer is generally best kept alone due to its territorial nature and powerful bite. Most community fish are unsuitable, and even large tank mates may be injured.

Species-only aquariums provide the safest and most successful long-term environment for this remarkable fish.
