Glowlight Tetra [A Few Interesting Facts]

Glowlight Tetra

Glowlight Tetra is a small tropical fish from the Essequibo River in Guyana, South America. Its scientific name is Hemigrammus erythrozonus.

This peaceful fish likes to swim in groups and is bigger than neon tetras.

It’s great for community tanks because it gets along well with similar-sized, non-aggressive species.

Red-line rasbora looks like the glowlight tetra but isn’t closely related since it belongs to a different family.

Glowlight tetras can live for 2 to 4 years if taken care of properly. In their natural environment, these fish feed on insect larvae, worms, small crustaceans, and plants.

Glowlight tetras should be kept in groups of at least five in an aquarium that’s at least 60 cm (24 inches) long for optimum health.
