Tetraodon Baileyi

Datasheet

General Description

Puffer fish, specifically the Hairy Puffer (Tetraodon Baileyi), are known for their ability to inflate their stomachs as a defense mechanism. Possessing the deadly neurotoxin tetrodoxin, similar to the blue-ringed octopus, they are notorious for their toxicity. The Hairy Puffer, a relatively rare species in the aquarium trade, can change colors based on mood and lacks scales. It can reach sizes of up to 12.0 cm and is native to Thailand and Laos.

Aquarium Setup

For the Hairy Puffer, a tank size of at least 70 litres with a biotope setup is recommended, featuring a sandy substrate with smooth rocks for hiding places. Providing a moderate water current and maintaining water conditions of pH 6.5-7.5, hardness of 5-12°dH, and temperatures between 23-27°C are crucial.

Behaviour

Hairy Puffers are inherently aggressive and territorial, often displaying hostility towards other fish, including conspecifics. Due to their beak-like mouth that can cause severe damage, they are best kept alone to prevent harm to tankmates.

Feeding and Diet

Feeding on shellfish, worms, and other live/frozen foods, Hairy Puffers require regular intake of snails and unshelled shellfish to grind down their continuously growing teeth. Maintaining sharp teeth is essential for their well-being.

Reproduction & Dimorphism

Reproduction of the Hairy Puffer in captivity is uncommon, likely due to their aggressive nature hindering breeding attempts. Males are believed to have more cirri (hair-like growths) than females, though this dimorphism is debated as some sources claim females lack cirri entirely.

Habitat and Distribution

Inhabiting rocky areas of large rivers, particularly those with whitewater, Hairy Puffers are found in regions of Thailand and Laos. Their natural habitat includes ample hiding spots within submerged rock structures.
