I need a heater for my 5 gallon tank. I will be getting a betta and 3 harlequin rasboras (if that makes any differeence) I don't know how many watts to get and i don't know much about heaters at all. Any help is appreciated!
I believe the smallest is a 50 watt, but ive heard rumours of a 25 watt heater yet those are kinda hard to find. 25 watts would be good, 50 be great too jsut get a good reliable one like a tronic or ebo jager.
I have one of those junior heaters from Walmart...would probably work, they're like 6 bucks. OR just spring for the 50 watt, you'll probably get a bigger tank you can use it in hehe
