Will this work for a 5.5 gallon with a male betta and not overheat?

It has consistently held 78 degrees in our 2.5 gallon tank since we got it. It will most certainly do it in your 5.5 gallon tank. It is the BEST heater ever. You will not be sorry with this purchase.

I'm using it in a 2.5 Gallon with a Betta....it works great! I used it all winter when our house temp. gets down to 65 degrees at night. The tank remained at a steady 80 degrees F. I don't use it in summer because our house stays at around 78. I recommend getting a thermometer as well....

Yes it will work. I have on in my 5.5 gallon filtered tank and this heater has been consistent with 80 degrees temperature for my betta tank. I got it seven months ago and it is still good. I highly recommend this heater! :-)

I have several of these in 2.5 and 5 gallon tanks with male bettas. Best heaters I have ever had.

This thing work perfectly ~ you set the desire temperature & you got it baby , it's not a cheap one from China ... It's about 10' long !

I bought the Aqueon AQ10W. It seems to work quite well. It is about $15. I do not like that it is automatic and in summer it keeps the tank a little warm (about 85F). It doesn't seem too hot for the bettas, would prefer to be closer to 80F but they seem healthy and happy.

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 breed bettas and would never recommend this heater. I had these in 2 1/2G tanks and found it to be very unreliable. You are so much better off getting a heater that you can set the temperature on.

Any of the small 7.5 or 8 watt "Betta" heaters work well hidden in the pump area of the tank. Be aware these heaters are always ON, they do not have thermostats, so you must keep a thermometer in the tank to monitor the temp. On very warm days the tank may get too hot unless you unplug these. You can purchase a seperate "heater controller" to act as a thermostat, but they are a bit pricey. Most heaters w/thermostats are too bulky to fit in the filter compartment.

I have not purchased this item and will never do so. One being that it is not worth it for what it is... Second that is is stressful on the fish being that they can see each other. Third, this is much too small to comfortably house three bettas. A single betta for this volume of water would be best. This is not to say that you can't house 3 bettas in such a small tank, but that it would be best to provide 2 1/2 gallons or 5 gallons minimum per fish. Maintenance may also be a problem. A single betta in a 5 gallon tank that has been cycled, has a heater, and is filtered would be best. Or you can divide a 5 gallon in two with a divider that prevents either betta from seeing each other or getting past. If you want companions for your betta, do some research online.

Yes, it will. I have it in a 5 gal tank now. Before that I had it in a 3.5 gal. tank. The water flow adjusts but, I leave it on high in my 5 gal. It works very well.

Absolutely overkill for a 5 gallon tank. You need a 50watt at most. A 150watt would likely cook the little guppies.

NO...it will get way too hot!! I had this in my 2.6 G Fluval and raised the temp to 86. MAYBE you could try the 5 watt but better to go with a little betta heater made for that size.

I have this in a 5 gal and it has worked wonderfully for my Betta. I added a good filter and cycled it first. Curious as to what you would put in a 1 gal, the smaller the tank the harder it it to maintain and it requires almost daily water changes when this small

Mine works great in my 5 gallon goldfish tank. I'd only hesitate using it for bettas because sometimes water currents can damage their delicate fins.

I wouldn't recommend it, I used it for a 3 gal tank and it heated it to almost 78-80 degrees sometimes. Luckily I had a thermometer on the outside side of the tank so I just unplugged it if it got too warm. I just had one Beta fish in the tank, if you have any other fish other than a goldfish or a guppy I would definitely try to get a bigger tank so you can put a heater in it :) Hope this helps!

I use the 50watt in my betta tanks. (One gallon) and since its preset it shouldn't be to hot.

Yes this should easily be able to keep a small tank heated and the digital read out is really convenient. My suggestion though would be to measure your tank and make sure it is tall enough to accomodate the heater. Ours is just tall enough and it is a 10 gallon tank.

It's a bit weak for a proper 5 gallon tank. Go for the Hydor Theo 25 watt submersible. It has adjustable temperature settings and doesn't cook my snails when they crawl over it.

Well it overheated my 5.5 gallon and killed my fish so it would probably do the same to a 3 gallon. Please do not buy...

yes, I very much like this one; Hydor 7.5w Slim Heater for Bettas and Bowls, 2 to 5 gal It works well without cooking your fish.
