Overview

The Red Eye Tetra (Moenkhausia sanctaefilomenae) is a classic community fish known for its clean silver body, bold black tail accents, and signature red-ringed eyes that stand out in motion. Tank-bred specimens are especially hardy and adaptable, making them an excellent choice for both newer aquarists and experienced hobbyists alike.

When kept in groups, these tetras create a strong, unified presence in the aquarium. Their steady, confident swimming pattern brings structure and rhythm to open water areas, making them an ideal species for balancing planted layouts.

This is a fish that does not rely on extreme coloration to stand out. Instead, it brings contrast, movement, and consistency to the aquarium as a whole.
