**Red Eye Tetra (Moenkhausia sanctaefilomenae) for Sale in Canada**

The Red Eye Tetra (Moenkhausia sanctaefilomenae) is an attractive and active South American freshwater fish recognized by its bright red upper eye area, shimmering silver body, and distinctive black-and-white marking near the tail. Hardy, social, and energetic, this species is a popular choice for spacious community aquariums.

A healthy school of Red Eye Tetras creates constant movement in the middle areas of the aquarium. Their reflective silver bodies catch the light beautifully, while their red eyes and contrasting tail markings give them a distinctive appearance.

Red Eye Tetras are generally peaceful, but they are active and can grow larger than many popular nano tetras. They appreciate adequate swimming space and are best kept in a proper group with similarly active and appropriately sized tank mates.

Monster Aquarium Canada offers Red Eye Tetra (Moenkhausia sanctaefilomenae) for Canadian aquarium hobbyists with professional live fish shipping throughout Canada.

Schooling Behaviour

Red Eye Tetras are social fish and should be kept in groups.

Recommended Group Size

Keep 6 or more, while 8–10 or more can provide a more impressive and natural schooling display.

A proper group encourages:

Greater confidence
Reduced stress
Natural social behaviour
More coordinated swimming
Better overall aquarium activity

A larger school is particularly impressive in a spacious planted aquarium.

Male and Female Differences

Sexual differences are generally subtle.

Males

Often appear slimmer
May be slightly more streamlined

Females

Usually have a fuller body
May develop a rounder abdomen when carrying eggs

Sexing individual fish can be difficult, especially when they are young.

Supporting Healthy Color and Appearance

The Red Eye Tetra’s attractive appearance depends on good health and proper aquarium care.

Care Tips

Maintain excellent water quality
Feed a varied diet
Keep an appropriate school
Avoid overcrowding
Provide open swimming space
Include plants and natural cover
Minimize unnecessary stress

Healthy fish should display active swimming behaviour and clear, attractive body markings.

Breeding Red Eye Tetras

Red Eye Tetras are egg-scattering fish and may breed under suitable aquarium conditions.

Breeding Tips

Condition healthy adults with live and frozen foods
Use a separate breeding aquarium
Provide fine-leaved plants or spawning mops
Maintain clean, stable water
Use subdued lighting
Remove adults after spawning
Protect eggs and developing fry

Adults do not provide parental care and may eat the eggs.

Raising Fry

Newly hatched fry require extremely small foods at first before gradually moving to larger foods as they develop.
