The suitable water temperature range for neon tetras is between 24 and 26 degrees Celsius. Within this temperature range, neon tetras grow best and their coloration appears most vibrant, making them more visually appealing. Specifically, neon tetras have rather strict requirements for water temperature. They are suitable for living in water with a temperature between 24 and 26 degrees Celsius, and the optimal growth temperature is 24 degrees Celsius. The fluctuation of the water temperature should not be too large, otherwise, it will affect their health.
In addition, neon tetras also have certain requirements for water quality. They are suitable for living in soft water. The pH value of the water should be between 5.5 and 7.0, and the dGH should be 2.0 to 4.0N. During the breeding process, direct strong light should be avoided, and some aquatic plants should be appropriately planted to block the light. Neon tetras don't have high demands for food. You can choose suitable artificial fish food for them, and they can also be fed with bloodworms, tubifex worms, dry food, and so on.
