This is the most common disease among neon tetras. The first sign is swimming away from tankmates. Affected tetras will also lose their neon stripe and develop spots or cysts on their dorsal fins. As soon as you recognize early symptoms, relocate the sick fish to a quarantine tank immediately. The disease is almost always incurable, but it never hurts to ask the vet for advice. It's normal for neon tetras to become dull in color at night. This is the result of special skin cells called chromatophores taking a rest. However, if the dullness continues during the day for several days in a row, the fish may be ill. Ich is a highly contagious parasite that takes the form of small white cilia-covered spots on the fish's body, which look like salt. To fight it, slowly raise the tank temperature to at least 86F (30C) for three days. This should kill the parasite. If the spots don't disappear after three days, put your fish in a quarantine tank and add cupramine (copper solution) to the water. Follow the instructions on the label. Keep the copper levels at 0.2 ppm. You can measure copper levels with a salifert test kit that you can buy in hobby stores. Kill the Ich in the original tank with aquarium salts, which you can buy in pet supply stores. Add one teaspoon (5 g) per gallon (4 L) of water every 12 hours for 36 hours. Let the salt remain in the tank for 7 to 10 days. If you have plastic plants, aquarium salts will melt them. For the sake of your tetras, toss the plants. Unhealthy neon tetras can also develop skin flukes, bacterial infections and diseases, and parasitic infections. Talk to your vet or read books that detail the symptoms and treatments of all diseases your fish might develop. In many cases, catching the early symptoms and taking immediate action can save your fish.
