Glowlight Tetra (Hemigrammus erythrozonus)
The Glowlight Tetra is a peaceful schooling fish named for the bright orange-red stripe that runs along its body, resembling a glowing filament. Hardy and active, these tetras make excellent community fish and show their best colors when kept in planted aquariums with slightly subdued lighting. Their shimmering, reflective scales give them a gentle glow that makes them stand out in groups.
