is this heater suitable for a 1/2 gallon tank? if not, can you recommend any that are?

No, it will boil any fish in it. Grab a slightly bigger tank (no fish can go in a 1/2 gallon healthily) and no heater will work well for such a small size :(

Hello RaeRae, You answer is not so simple. The capacity of a heater not only depends on the heater itself, but the original temperature of the medium. Even though this is rated for a larger tank than you are asking about, if the place the tank will be in much colder than average is may be a good choice. If your water starts at 65 degrees, and you want it at 78, this may work for you. If you start at 72, this may get the water hotter than you want. Another aspect to consider is how much water movement you have in your tank. The more water movement, the better the heat will be distributed, and the water will be closer to the thermo's temp setting. I agree with JR, I have not seen any for that small of a size. You could look at reptile heating accessories that afix to the outside of the tank, it would be a hack though.

Hello. I wanted to start by noting the heater I received is not the one in the picture. It is shorter and thicker, and only has one suction cup at the top.That said, I bought this one because it was the lowest wattage I could find for my 1 gallon tank. The recommendations I found said 7 watts for 1.5 gallons and up, 5 watts for 1 gallon and up. I have not seen any for smaller tanks than that.

I don't believe so. Mainly these mini heaters are intended for 1 gallon tanks and up, anything smaller will cook whatever you have in there. I think you'll be fine without one. I keep my Betta's in gallon cylinder glass containers in room temp and sometimes colder and they are perfectly fine.

I think this works for up to a 5 gallon tank. It might not matter too much about the extra 1/2 gallon though this filter ha a lot of power!

must be a pressure demand. I use mine on a 5 or 7gal tank and it works fine. I have noticed that it automatically cuts off after about 1/2 hour. I like that but didn't see anything stating that this is supposed to happen. I have been pleased with the heater.

i am using mine in a 2 1/2 gallon tank. & i had to take the plastic stem out in order to make it fit. I fitted it with a plastic aquarium plant pot covered with plastic mesh & it works great.

There's multiple sizes selectable here. I prefer yo run two undersized heaters so if the thermostat goes bad i in one it won't cook the fish. For a 39 gallon I'd think you'd want like two 100w heaters.

I have this heater in a 1.5 gallon tank and it works perfect. I keep a temp. Strip on the outside of my tank to keep track and it's always at 78 which my betta seems to be happy with. I live in Washington and we don't use our heater so the house stays pretty cold.

This "tank" is only 2 gallons and the surrounding air in your home should be warm enough for any fish that would be suited for this little tank. Also, it's plastic, a heater would probably damage it...

I have been using a cheap $10 tetra heater. Have had no problems for 6 months so far. But the led lighta on my tank are quitting one by one. Im a bit disappointed in that because the tank was so expensive.

This *might* work for 2 gallons, but is listed for 1.5, which hopefully would work. I tried this yesterday to heat a 2 gallon tank and it could not get it over 76 degrees, which is not warm enough for a betta, which is what this heater is supposed to be for. I am sticking this one in a closet and using a 50W PetCo brand heater that is meant for 2-10 gallon tanks and has an adjustable temperature.

I returned a 7.5 watt pad type heater, and the Marina C10 heater, for the Cobalt Aquatics 10-Watt MIni-Therm Electronic Heater. The Cobalt gets better reviews for keeping 2.6 gallon tanks warm in cold rooms. The heater can fit in the filter canister.

I'm using it in a 3 gallon Tetra Cube. As long as it's submerged horizontal or vertically, and not touching substrate, it'll work. The heater is 6.5" tall x 2" wide. I like it because, it heats to a set temperature; if the tank is too warm, it shuts off. I've been using it for a month, checking with a thermometer, and it's been spot on 80, as set for my Betta.

Yes it is. I used mine in a 2 gallon acrylic tank for a Betta , and it worked fine. I recommend checking the heater periodically to make sure it's working properly.

I'm not sure about a tank that small. As long as there is enough water to cover the heater and keep it cool I'm sure it would work.If you decide to try it I would recommend getting a submersible thermometer and monitoring the temp to ensure it doesn't get to warm.

This heater will be overkill for a 1 gallon tank. There are very few heaters that are designed to work well in a 1 gallon tank. Can you choose a larger tank? Larger tanks will more water volume will be more stable in every parameter - leading to improved livestock and plant health, as well as easier maintenance.

I have the 12 gallon and it doesn't have a heater but one can be purchased for either size from Amazon Fluval EDGE 6 Gallon Aquarium - FLUVAL EDGE 25W COMPACT HEATER

I have a 20 gallon aquarium also and I have a 100 watt but you could probably get away with a 50 watt. I always set the heaters up vertical so really couldn't tell you on that

Hi. In all honesty i don't know what heaters to use precisely, because the fish that i get don't really need the hearter. I avoid getting high maintenance fish for this tank. I figure its small and simple. So if i was you, i wouldn't get expensive fish. The fish i have is 1 albino pleco, 5neon barbs, 5zebras skinny fish.Thats it. &the tank looks great. They alive since jan 2014.
