Questions & Answers

8 Customer Questions


Can this be put in a plastic tank?
Answer by ChewyApr 20, 2021
SunGrow Halfmoon Betta Aquarium Heater can be used for plastic tanks.

Are these safe for a 2 gallon aquarium?
Answer by ChewyAug 04, 2021
The betta heater can support up to 2 gallon tanks.

Can this heater be used on acrylic tanks or will it melt?
Answer by ChewyApr 12, 2021
This heater can be used in an acrylic tank.

What does a red light mean? Does that mean it's on?
Answer by ChewyMar 29, 2022
The light will show when the heater is on. When the water temperature is under 74°F, the aquarium heater starts working. When the water temperature reaches higher than 77°F , the aquarium heater stops heating. This ensures that the temperature stays constant between 74-77°F (24-25 ℃) which is the ideal temperature for Betta.

Stays too hot

I didn't want a non-adjustable heater for my 3gal tank, but had trouble finding one that didn't have crappy reviews. This one keeps my tank at 81°, just like other reviewers have stated. Too warm for my fish. I'm disappointed and will be returning this once I get a replacement.

Works Great

I ordered this for my 1.5 gallon betta tank and it keeps the temperature within the required range. It is small so it does not take up much room in the tank. My betta has taken refuge at the top of it, which is odd because he has plants, leafs, and a tunnel to hide in.

perfect for betta

I bought this to keep my betta warm as we keep our house a little cooler in the winter due to heating costs. This was a perfect choice. Easy to use and quick to install. I took off 1 star because I thought it came with a thermometer on it but it doesnt, and because its on the bigger end and a bit too large for a 2gal tank.

Lights up but doesn't get warm

The heater lights up but after a few hours in the tank, the water is the same temperature as when I put in and when I touch the heater, it isn't even warm. I have a gallon and a half size tank.

Great quality

Had a hard time deciding on a heater because of all the scary reviews I've come across. I've had this one for five months now and it's still working great! I bought 2 so I have one for each of my fish tanks and I haven't had an issue with either of them.

I received the water heater but it is missing the thermostat! Pls send the thermostat

Keeps them toasty. Maybe too toasty.

This heater is keeping my now fishless cycling tank at a toasty 82 degrees F, a little on the warm side. I am probably going to find another small heater in store and keep this one as a back up, as it hasn't dropped below 81 degrees F

Electric Shock

This heater seemed to work fine for a while. Then our betta fish started acting weird. He would hide in his house and only come out to eat. My husband put his finger in the water when feeding the fish and got a shock where he had a cut. He thought it was something in the water but when he poured the water over his cut he felt nothing. He unplugged the water heater and put his finger in the water again and no longer received the shock. The fish immediately started acting normal again, swimming around freely and no longer hiding.

Its getting hot in here

I got this nice lil heater for a 5gal tank. I do wish there was a switch to turn the temp down, since thermometer says fish tank is 80. Luckily I don't have a fish yet since I was letting the tank cycle.
