Good Heaters For 5.5 Gallon?

So for Christmas I got a 5.5 gallon aquarium which was great. I cycled it, upgraded it from the crappy filter the set came with (I got an aquaclear 20 instead of the top fin 10 it came with) but the problem was I couldn't find a strong heater. I have a 10 watt heater in my 3 gallon and it keeps it at like 80-82 degrees which my betta likes (he is spoiled with heat, if you even turn off the heater to change the tank he just lays on the bottom staring at you) so I just put my extra 10 watt in my 5.5 gallon tank. It keeps it at about 78-79 degrees which is a little cool but my betta doesn't really seem to mind (I don't think atleast, I can't really ask him if he wants the water warmer) but the other day I saw a tetra minI 25 watt heater at a small pet store for like 27$ which is sooooo much better compared to the massive 25 watt heaters for 50$ at petsmart! It would take some convincing to make my parents let me buy it but it is my money and I've been saving money it to get YazI (the betta in the 5.5 gallon) something nice. So what do you think??

I have the same aquarium as you, and I use a Tetra 2-15 gallon submersible heater. I got mine at PetSmart, so you can find it there or at another LFS probably. It works great and sets the temperature to 78° F (25° C) It's around 15-20$.

 

For my 5.5g betta tanks I have jager eheim 50watt heaters. It's a kinda over kill for that small tank but it stays at 80-82F all the time and rarely ever turns on so it's all good.

 

Thank you you guys! I will probably go out and get the tetra minI one (its the cheapest one I could find and it still has good reviews I think) well atleast I will try to get it, depending on if my parents will let me

 

I use a 25w Marineland heater that came with my 10 gallon kit.

I have an Aquatop 15 watt in my 3.4 gallon.
It's preset at 78 degrees and has a thermostat built in.
They also have a 25 watt version.

I was looking at that one on amazon a little while ago, is it too tall for your tank? I measured my tank and it is a little too tall.

It is a little tall for the 5.5 tank but I just put it at an angle and it works fine. Ouncan have it completely submerged too so you can put it along the bottom of the tank, cover it with plants/decor and it'll be fine
