The Lemon Tetra (Hyphessobrycon pulchripinnis) is a species of small tetra originating from Brazil. They are characterized by their clear, light bodies, red eyes, and yellow splashes of colour on their fins.
These tetra species are ideal for the beginner. Their hardiness and adaptability make them a very good option for many peaceful aquarium set-ups.
They are a schooling fish, so they should be kept in groups of at least 3 (but more is always better). A group of 6 Lemon tetra can be kept in aquariums as small as 10 gallons. This fish species requires a water temperature between 71-81 degrees Fahrenheit and will accept a pH range between 6.0-7.5. While their natural environment is slightly acidic, domestication has made these fish hardy enough to thrive in neutral and even slightly alkaline water. These fish grow up to 2 inches in length and can live for up to 8 years in captivity.
The Lemon Tetra is an omnivore and will eat most commercially available fish foods. We recommend alternating between pellets, flakes, and frozen foods such as brine shrimp for best colours and health.
This species is very well-suited to the peaceful community aquarium and can be kept with most other tetra species, bottomfeeder species, and livebearers without an issue. They will not attack fully-grown dwarf shrimp species, but they will hunt and eat baby dwarf shrimp.
