Material and Durability

The material of the heater was another important factor. I opted for a heater made of high-quality glass or durable plastic, as these materials tend to withstand the aquatic environment better. I wanted something that would last and not corrode over time.

Safety Features

Safety features were non-negotiable for me. I looked for heaters with automatic shut-off mechanisms to prevent overheating. Additionally, having a heater that is resistant to breakage gave me peace of mind as I didn’t want to risk harming my fish.
