Is the glass hot for baby fry fish?

Answer by Chewy • Nov 21, 2023
If the heater is submerged under water, it will not harm the fish. Also, make sure the heater is being used in the correct size aquarium. The optimal aquarium size for this 50-watt heater is 15 gallons.

Still working

This is the first heater I have bought that is still working like it should. Hopefully it lasts more than a month.
