Aqueon Pro Heater
A reliable adjustable heater for tropical tanks. Most aquarium fish are tropical and quietly suffer in unheated, temperature-swinging water.

Our take
Nearly all popular aquarium fish, tetras, guppies, bettas, are tropical and need stable warmth in the mid-to-high 70s Fahrenheit. Room temperature swings stress them and invite disease, yet a lot of first tanks have no heater at all. This one is adjustable, shatter-resistant, and shuts off if it overheats or is lifted out. Match the wattage to your tank size, roughly 5 watts per gallon, and pair it with a separate thermometer, because you should never trust the heater's own dial blindly.
