Neon tetras are relatively easy to raise, but they require specific environments and conditions.
Neon tetras are suitable to live in water with a temperature of around 22 to 24 degrees Celsius, and the appropriate temperature range is 24 to 28 degrees. The pH value should be between 6.5 and 7, and the hardness should be KH 10 - 15. They have relatively high requirements for water quality. It's necessary to keep the water clean and avoid using chemical cleaners, so as not to affect their health. Neon tetras prefer live feed such as water fleas and tubifex worms, and sometimes they can also be fed with dry feed.
Neon tetras are gentle in nature, they don't bite or fight with each other. They like swimming in groups and are suitable for being raised in groups. They need a quiet environment. When they move in the water, they will emit red or green lights from time to time, which is really beautiful. They are often called "the queen of tropical fish".
