Neon Tetra Tank Requirements
The neon is used to the warm waters of the South American seas. The same should be mimicked in its tank. A 20 gallon tank is ideal for neon tetras unless you planning on having a big school of neon tetra. A bigger tank is necessary then. Remember to use mature tanks since recycled ones may not auger well with them. Provide a sandy substrate on a gravel base. Pebbles can be used too. Ensure the substrate is darker as this is what is present in their wild habitats. A good choice would be ADA Aqua Soil Amazonia Substrate.
Rooted plants suh as java fern can be added too. Since they love swimming in the middle of the tank, they are unlikely to interfere with plant roots. Also, their size does not allow them the stamina to uproot plants. Keep water temperatures at 70F to 80F and the pH level should be below 7.0 but should not go below 6.0.
