About this product
The box holds one AQUANEAT 25W aquarium heater measuring 4.5 inches, plus a suction cup and a thermometer strip. The heater is preset to 78°F and is meant for small tanks holding 3 to 5.5 gallons. Its size suits a fish tank or a fish bowl of that range.
What comes in the box
- One 25W small aquarium heater, model G405, in black
- One suction cup for mounting
- One thermometer strip
How the heater works in the tank
The heater draws 25W and holds a preset temperature of 78°F, so there is no dial to adjust. The manufacturer describes setup as plug and play, with no extra steps before it goes in the water.
A light on the unit shows what the heater is doing: it turns red while heating and green while resting. The 4.5-inch body sits inside the tank, kept in place with the supplied suction cup.
Does it fit your tank?
Check the water volume first, because the manufacturer gives this heater a range of 3 to 5.5 gallons and it is not intended for tanks outside that range. Measure the space where the heater will sit as well, since it is 4.5 inches long.
Two placement rules come with the unit: keep it fully submerged under water before plugging it in, and unplug it and wait at least 10 minutes before tank maintenance or before taking it out of the water. The heater should not be touched while it is powered on.
What buyers mention
Several reviewers say the heater fits well in small tanks and a few note that its compact size takes up little room. Temperature stability comes up too, with some reviewers reporting a consistent temperature. A separate group of reviewers mentions that the suction cup comes loose, and a couple describe the setup as plug-and-play.
Questions buyers ask
What size tank is this heater for?

What is included with the heater?
The box contains one 25W heater, one suction cup and one thermometer strip.
How is it installed?
Submerge the heater fully under water, then plug it in; the manufacturer states no extra setup is needed.

What customers say
Customers find the aquarium heater works well, particularly in small tanks under a gallon, and appreciate its compact size, especially for 1-gallon tanks. The temperature control receives mixed feedback - while some say it holds at 78 degrees with no problem, others report it takes too long to warm up. The heater's durability and quality also get mixed reviews, with some finding it durable while others report melting issues, and opinions on value are generally positive. The secure fit is a concern, with multiple customers noting it won't stay locked into the suction cup.
