What to know before you buy.
A very active and fast-swimming species, the Blue Tetra has a subtle iridescent blue sheen that becomes more vibrant depending on the lighting and mood. They can be slightly nippy, so they are best kept in a larger school and with robust, fast-moving tankmates. Their energy makes for a lively display.
