It is not recommended to keep neon tetras in a 3.5-gallon tank as it is too small for them. Neon tetras are active fish that require ample swimming space and a well-maintained environment to thrive. A 3.5-gallon tank is suitable for only a few small shrimp or snails.
In general, the rule of thumb for stocking a fish tank is to allow one gallon of water per inch of fish. Neon tetras can grow up to 1.5 inches in length, so a minimum of 5 gallons is recommended for a small school of 3-4 neon tetras. However, a larger tank of 10 gallons or more is preferable as it provides more swimming space and allows for a more stable environment.
Overcrowding a small tank can lead to poor water quality, stress, and disease among the fish. It can also make it difficult to maintain the water parameters, such as temperature and pH, which are crucial for the health of the fish.
In addition to the tank size, it is important to consider the filtration system, lighting, and decoration of the tank. Neon tetras prefer a planted tank with plenty of hiding places and a gentle water flow. They also require a consistent temperature between 72-78°F and a pH level between 6.0-7.5.
Overall, a 3.5-gallon tank is not suitable for neon tetras. It is important to research the specific needs of any fish species before purchasing them and to provide them with a suitable and healthy environment to thrive in.
