Overview

The lemon tetra is a peaceful schooling characin for a planted community tank. It is an easy fish to keep.

Did you know

In a tight group, dominant lemon tetras flush their fins with deep black-and-yellow edging during display, while subordinate fish stay washed out. The color of the whole school is a quick read on how settled and well-fed they are.

Caring for the lemon tetra

Keep lemon tetras in a group of at least six, and ideally more, or they get skittish and nippy. A school fits in 17 gal (65 L) or more. They are constantly active in the middle and upper water, so leave open swimming room among the plants.

A planted tank with driftwood, a darker substrate and subdued lighting brings out their color. Keep the water soft, at 72 to 82°F (22 to 28°C) and a pH of 6.0 to 8.0.

Feed small foods such as quality flake and micro pellets, with the odd frozen treat such as brine shrimp or bloodworms. Lemon tetras are peaceful, so keep them alongside calm tank mates. They are egg scatterers with no parental care. The eggs hatch in roughly a day, but breeding them is hard.
