2 Customer Questions

What do the different colors mean? Does blue mean that’s the current temp?

Answer by Chewy • Feb 20, 2022
This sticker is designed using black with white numbers making it easy to read—while reading the temperature is designed to appear in blue so that you can easily see it.

Will this stick to a plastic betta tank?

Answer by Chewy • Jul 28, 2023
To be the most effective, the sticker betta thermometer should be stuck to the outside of your betta tank away from any heat source such as light bulbs or heat pumps. This ensures you receive the most accurate reading and can adjust your water temperature accordingly.

Garbage

You cannot read the thermometer in a lower-light area without turning a flashlight on it. I haven't had it more than a month and it fell apart and no longer registers

You cannot read the thermometer in a lower-light area without turning a flashlight on it. I haven't had it more than a month and it fell apart and no longer registers the water temperature at all.

Garbage

Small-sufficient but dark to read

Once you stick it on you can't remove it or it'll rip
