Neon Tetras are a small community fish. They only grow to about 1.5 to 3 inches or so when fully grown. Since tetras are a schooling fish, they prefer to be in a school of other tetras. They are also very colorful and fun fish to watch swim around your tank. In addition to having a good small shape and being colorful, they are also inexpensive which make them a top choice for small aquariums.
You would need at least 6 – 10 Neon Tetras as that’s the maximum you would want to stock your 5-gallon tank with.
What Is The Ideal Tank Size For Neon Tetras
Neon Tetras like to swim around in groups so while they are small you would think a smaller tank like 1-2 gallons would be ideal. However, keep in mind that they need room to move around in so I would at least start with a 5-gallon tank and no more than 10 fish.
