Compact warmth for small tanks

The SEAOURA 25W small aquarium heater is built for intimate spaces where steady, gentle warmth matters. Crafted with an explosion-proof quartz heating tube and a protective plastic cover, it aims to minimize risk while keeping fish, turtles, and other small residents at a comfortable temperature. Designed for 110-120 V outlets, it fits neatly into most 1–6 gallon setups without crowding the tank.

The result is a quiet, steady heat that supports calm, active behavior in your aquatic pets.

Clear, precise temperature control at a glance

A sensor delivers temperature readings with about ±1°F accuracy, and you can switch between Celsius and Fahrenheit with a simple three‑second key press. The combination of precise readouts and tactile controls helps you fine‑tune warmth to suit the moment, from a cool morning routine to a warmer afternoon in your tank care window.
