Amazon Puffer (Colomesus asellus)

Amazon Puffer (Colomesus asellus)

Quarantined specialty puffer for carefully planned freshwater aquariums in Canada.

The Amazon Puffer is an active South American freshwater puffer with a lively personality and constant movement. Unlike many larger puffers, it is often kept in groups, but it still requires special feeding and careful tankmate selection.

Why This Fish Stands Out

• Highly interactive oddball fish with strong personality
• Specialty species for aquarists who want behaviour, not just colour
• Best for a planned species-focused aquarium rather than a casual community tank

Aquarium Setup & Behaviour

Provide a mature, strongly filtered aquarium with stable water, hiding places, and careful long-term planning. Provide a mature freshwater aquarium with strong filtration, open swimming space, and good oxygenation.

Often best kept in a group of its own kind in a planned setup. Avoid slow long-finned tankmates.

Feeding

Puffers need a varied meaty diet and should not be treated as flake-food community fish. Hard-shelled foods are especially important because Amazon Puffers are known for needing regular dental wear through diet.

Natural Colour & Livestock Integrity

Colour and pattern come from the fish's natural appearance and healthy conditioning. Topick Aquarium does not use dye or hormones to artificially enhance colour.

Topick Aquarium Livestock Standard

All fish at Topick Aquarium are carefully quarantined and conditioned to our stable local tap water before sale. Some oddball and specialty species still have very specific long-term needs, so we recommend matching each fish to the right aquarium size, diet, tankmates, and maintenance routine before purchase.
