It’s understandable to be concerned about potential chemical exposure to your fish due to the broken thermometer. Thermometers might contain harmful substances, depending on the type.
- Identify the type of thermometer used
- Remove fish from contaminated water immediately
- Replace the water and clean the tank thoroughly
Most modern aquarium thermometers do not contain mercury, but if your thermometer is older, there could be some hazardous chemicals involved. It’s important to act quickly by relocating your fish to a safe, clean environment. Empty and thoroughly clean the tank, making sure to remove all debris. Always refill with treated water before returning your fish to the tank.
If this is an emergency, please seek immediate veterinary care.
