Amazon Puffer

Amazon Puffer (Colomesus asellus)

The Amazon Puffer, also known as the South American Puffer, is a lively and personable freshwater species native to the slow-moving rivers of the Amazon Basin. Recognized for its charming personality and bold, bumblebee-like stripes, this fish has become a favorite among aquarists who enjoy keeping puffers with attitude and intelligence. Unlike many of its more aggressive relatives, the Amazon Puffer is relatively peaceful and can be housed with other robust community fish under the right conditions.

This species typically grows to around 3 inches (7–8 cm) and thrives in aquariums of 30 gallons or more with open swimming space and plenty of hiding areas. They enjoy slightly acidic to neutral water with temperatures between 75–82°F (24–28°C) and a gentle current that mimics their natural environment. A well-planted tank with smooth driftwood and rocks creates a secure and stimulating home for this curious and playful puffer.

Feeding the Amazon Puffer is one of the joys of keeping them. They are true carnivores with small but constantly growing teeth, so a varied diet that includes hard-shelled foods such as snails, shrimp, and clams is essential. Supplementing with frozen or live foods like bloodworms and brine shrimp keeps them healthy and engaged. Unlike larger solitary puffers, this species often thrives in small groups, displaying natural schooling behavior and vibrant interactions when provided with enough space.

The Amazon Puffer’s charm lies in its intelligence and activity level. They recognize feeding routines, explore every part of their tank, and interact with their surroundings in ways that make them seem almost aware of their keepers. With proper care and diet, they can live for 8–10 years, becoming one of the most enjoyable and rewarding puffers to own.
