Tank mates for neon tetras
We checked neon tetras against all 149 other species in our database for water temperature, pH, size, fin nipping, predation and aggression.
Good tank mates for neon tetras include cherry shrimp, nerite snail, guppy, panda corydoras, bristlenose pleco and bronze corydoras. Avoid angelfish, common goldfish and oscar: angelfish can eat neon tetras: they're small enough to fit in its mouth once it's grown.
Neon tetras: 21–25°C (70–77°F), pH 5.5–7.5, adult size 3.5 cm (1.4 in), minimum tank 15 gallons (57 L). Full neon tetra care guide.
