5 Gallon Tank Best Heater For A Betta In A 5 Gallon Tank?

[Rheanna Kapoor]

So I have an Aqeon 10 Watt heater in my 5 Gallon tetra tank that I setup last night. My Veiltail Betta Darling is not in it yet, but it's been running all night and the temperature is only 77.4°F, and I know bettas should have 78°F, does the 0.7°F make a difference? What heater is good for this tank? I know I have heard of some good ones, but what is best for bettas?

I recommend aqueon adjustable heaters like you already have; here's a size chart for them that I've found really helpful

I believe the general rule of thumb is 3-5 watts for every gallon. So you would want at least a 25watt in there. I'd personally go with an adjustable 50watt. That's what I have in my betta tanks. You'd want the water to be 'at least' 78°F and up to ~82°F. I like this Aqueon Pro 50W.

Thank you I will see if I can get that!

It looks like it is sort of pricey, on Amazon.ca it was $43.99. I will see what I can do today.

you can check out the eheim jager 25w heater. its a bit cheaper. I have it in my 5.5g and works amazingly well, keeps the tank at 80f

I used the Aqueon 10 W when I was first setting up my tank. It kept increasing the temperature uncontrollably and when I unplugged it, would sink below the minimum. I opted to switch to the 50 W adjustable one and it’s served me well ever since. So yeah I would think adjustable ones would be the best.

^ seconded, look for adjustable heaters! PetSmart has a decent variety in store, but I imagine there's some cheaper options on Amazon.

I personally recommend using an Aqueon Pro 50w heater. I have 3 different Aqueon Pros (x2 100w and x1 250w) running for 2 years now and not a single one failed.

Eheim jager 50 watt is what I would go with.

I got a fluval marina adjustable 50w heater from amazon. except when I bought it a month ago it was only 10 bucks, now it's nearly 20. yikes. heard good things about the aqueon adjustable pro, but it's even more expensive. I think it usually goes on sale for big holidays (too bad canada doesn't have black friday -- I think?)

adjustable 50w heaters are the way to go for 5-10g tanks imo. my other 50w heater is a zarco (some chinese off-brand) and it works just fine too.

Thank you. My father had Amazon prime so if I get something off Amazon I can get it in 2 days! I see what u are saying about the 50W...my temp right now is 78.8°F for some reason...I don't know why but it is pretty good. We do have black Friday in Canada, but us has he most awesome deals! Like for my hamster, our friends asked if we need anytime from the us and I want them to get me simple aspen bedding because Canada has no good brands! Can u beileve it? I have heard of Zacro for a thermometer...So I assume it should be good quality as well. I have a problem though:
I put Darling in last night, but that's when she was doing the floaty-thing where she looks bloated even though I haven't even fed her yet, I can't explain it. (She was doing this thing before I put her in the tank). So now she isn't doing that...but She is having such a hard time swimming! Wherever she tries to go...she is pulled towards the filter and so she has been in the corner the filter is...this whole time! Why can't she just swim around? Is it because she's not used to the flow? Please help. And I think her swim bladder is still acting up cuz she has a hard time swimming up and down...So She is basically just in one spot, she looks like she is interested in swimming everywhere else though she has tried to go toward the anubis and moss balls but it immediately sucks her to the filter (She can't get sucked in, I believe *gulp*). I don't know why she is doing this...
