This temperature is very suitable for betta and most tropical fish. When the water temperature is lower than 78℉, the heater starts to heat and the red light is on. When the temperature reaches 78℉, the heater stops heating and the green light is on. DaToo will always maintain this comfortable temperature for your beloved fish!

Awesome little heater! I used it to keep my chickens water from freezing. It never stopped working even in the cold. We absolutely love it!
Mrs. Ramona Koss I –
I have been keeping freshwater aquariums on and off for almost 30 yrs. Heaters have always been the same tech they are now. The BIG takeaway is to keep them cool and constantly sampling flowing water. I have ALWAYS set mine up by the pump outflow and kept them completely submerged. DO NOT keep them plugged in while changing water. This lowers overheating and temperature component shock which leads to a lot of the issues seen in the reviews here. If you have a betta in a setup with no water flow… do not get a heater until you have an actual tank setup. STOP putting these in bowls and expecting them not to blow up.Temperature accuracy and what I have learned with this unit… I keep mine in the pseudo sump unit in the 5 gallon kit I bought. This way water is constantly flowing around the unit. I have an air stone in this same compartment and when it is running it cools the unit more which lead to it running between 80 F – 78 F. When the bubbler is off it cycles and stays a consistent 78 F. So, over agitation can lead to the unit sampling too cool and cycling more. So, I have put my bubbler on a timer and do spaced out 30 min cycles throughout the day. This has resolved the issue with this unit. It needs gentle water flow for accurate sampling and heating. Over agitation can lead to it falsely reading the water as cooler leading to the varied warmer temps.

I’m on day 2 with this is my tank.. it holds the water temp between 78°F and 80°F. So far my issue is with the suction cup not holding to the side of the fish tank. I’ve had to place it back on the side of the tank twice already. I’m really hoping it doesn’t bust, as I’ve been reading several reviews that the glass tube busts and one has busted the fish tank ? if it keeps coming off the side of my tank, I’m going to have to look for a more expensive heater for my black orchid betta.

This is a very nice simple fish tank heater, I use it for when I’m making new salt water for a water change in my reef tank, I do 3 gallons at a time and this little heater has no problem getting the water to just the right temperature.
