JBJ Nano Arctica Chiller (10-20G) - Quiet Cooler for Axolotls, Goldfish & Shrimp

🏆 2026 Global Pet Expo Best in Show Winner

Keep your ecosystem stable and cool. The JBJ Nano Arctica E-Chiller is a compact thermoelectric cooling system designed for nano aquariums up to 10 or 20 gallons.

High-output lighting and seasonal room heat can quickly push a small tank out of balance. This unit helps regulate temperature and reduce sudden swings, supporting healthier livestock and a more stable aquarium.

This item ships separately via UPS Ground, and shipping is included in the price.

Aquatic Arts Insight

In nano aquariums, water volume is limited, which means temperature changes happen quickly. We like this unit because it is a complete system. It includes the pump and plumbing, so there is no guesswork when setting it up.

It is a reliable way to help maintain cooler, stable conditions for axolotls and sensitive shrimp without the size and noise of a traditional compressor chiller.
