Is the heater USB plug-in or for an electrical outlet?

Answer by • Sep 01, 2022

This heater has a US electrical outlet plug.

Is this suitable for a beta fish?

Answer by • Sep 14, 2022

This heater will work on glass or plastic tanks that are between 2 and 5 gallons. It is set to 77 degrees and is not able to be changed. If these are the parameters for the betta tank, then this will work.

Does this come with a power cord ?

It’s the right size for a small aquarium. It hold the constant temperature of 78 degrees in my 2.5 gallons for my baby guppies. The only downside is, the suction cups don’t hold. I have to adjust them every single day.
