The content on Inside Aquatics is general information about the freshwater aquarium hobby. It is not professional, veterinary, or safety advice.
Fish are living animals, and their care depends on the specific species, your water, and your setup. For a sick fish or a health concern, consult an aquatic veterinarian. Information here is a starting point, not a diagnosis.
An aquarium combines water and electrical equipment. Follow the instructions for your heater, filter, and lights, keep electrical connections dry, and use your own judgment. Local conditions and manufacturer guidance always take priority over anything written here. You are responsible for your own safety and the welfare of your fish.
