Aqua One Heater Protector
The Aqua one heater protector is capable of fitting other brands of heater, but it is preferable to fit an Aqua One heater inside of it.
Prevents fish from resting on the heater & getting burnt, so does what it is supposed to do.
This has successfully stopped my Featherfin Catfish lying on the heater and getting horrible burns down his side - he obviously isn’t a fast learner as he kept doing it!!
