But, a tank of 15 to 20 gallons is even better for a small school of 6-8 fish. Substrate should mimic their natural riverbed, with a mix of fine gravel and sand to create a natural, earthy look. Lighting should be moderate, with a combination of ambient and spotlighting to replicate their shaded forest stream environment. Lush, live plants are essential, providing hiding spots and oxygenating the water. Suitable options include Anubias, Java Fern, and Cryptocoryne.
