This is not a heater for your tank. This heater doesn't keep your tank at a constant temperature, it will just add heat until it is well over the threshold your tank should be at. Bettas need their water to be at a good 76-78 degrees, and this heater will heat your water to well over 85 degrees. Do not but this, spend the extra money to get a heater that is temperature adjustable or has a pre-set temp., otherwise your betta will fry.

I used this in an 3 gallon tank. There was no measurable temperature difference and the fish circled around the heater. It only made the fish look miserable and made me waste some money.

Rated 1 out of 5 by bettagirl9 Doesn't work well.
I would advise buying a different heater. This one only raised my temperature 2 degrees and my poor fish stayed near the bottom of the tank right by the heater.

Rated 1 out of 5 by LunarRolex no good
I got this to heat up my betta's fish bowl which is actually less than 1 gallon. In the end no good, it hardly produces any heat. For a second I thought it wasn't working but putting it to my hand I hardly felt any heat and what little it gave off was not distributing evenly.
