Does this device need to be plugged into electric socket?
Answer by Chewy • Aug 16, 2019
This mini heater does need to be plugged into an electrical socket.
Does the heater automatically shut off when water is right temperature
Answer by Chewy • Sep 21, 2020
This heater does not have a preset temperature. It will keep your tank around 6 to 8 degrees above room-temperature.
How do I know its on? There is no light.
Answer by Chewy • Sep 06, 2020
As a precaution, we always recommend using a thermometer to check your water temperature. The unit is equipped with a thermal cut-off safety fuse that will turn the heater off automatically if the unit overheats such as by being left out of the aquarium.
Can this be used in an acrylic tank?
Answer by Chewy • Jul 17, 2019
This heater is suitable for glass and acrylic tanks.

Mini Heater a life saver

My house has been pretty cold this season. My furnace is on the blink and new one will take a few weeks. I'm dressing warmer, furry pets have sweaters and heated beds but my Betta was looking sad, hanging out at the bottom of his 1.5 gal. bowl, not active, loosing color. I put the 5 watt heat in & it made a huge difference. Beautiful Finneas is now swimming around, eating better and loves to lay on his Betta Bed Fish hammock (also from Chewy-best 3 bucks I've spent-feel bad I didn't know about these for my prior Bettas) near the heat source. Make sure to get the correct wattage for the size of the fish aquarium/bowl.

Came home from 2 days away and all that was left was bones. The water was so hot! I feel terrible!

My mistake

I was browsing the different heaters for small aquariums. I had intended to get a larger one, but ended up with this one by mistake. Even so, I decided to move forward with heaters that have a set temperature, rather than these vague little things.

It works Fairly well.

I have this on a 2 gallon betta tank and it works okay, it's just very dependent on what the temperature in the room is as to what the temperature in the tank is, the water temperature is about six degrees warmer than the room temperature. It also lacks an on/off indicator light.

Caution When Using

I purchased this from a physical store for a new 2.5 gallon tank. I was wary because of reviews.
