Can Freshwater angelfish Live With Neon tetra?

The angelfish is a generally peaceful cichlid and a good community fish, but it may eat small fish such as tetras. A neon, at about 3 cm, is exactly that kind of small tetra, and an adult angelfish reaches 15 cm in body length.

The water is a tighter fit than it looks. Angelfish want 24 to 30 °C and neons 21 to 25 °C, so the two share only 24 to 25 °C, with pH 6 to 7.5.

If you keep them together, keep the neon school large, 8 to 10 or more, in a densely planted tank, and accept that a grown angelfish may take some. Neons colour up best in soft, acidic water over a dark substrate with subdued light, which an angelfish tank with tall plants and dim to moderate lighting already provides. Medium-to-large characins remain the better choice of tetra for an angelfish.
