Red Line Lizard Tetra

Red Line Lizard Tetra – Epalzeorhynchos frenatum

The Red Line Lizard Tetra is a small, active freshwater fish notable for its slender, streamlined body and the vivid red stripe running along its side, giving it a sleek, striking appearance. Its lizard-like shape and mid-to-top swimming habit make it a dynamic presence in planted and community aquariums.

This species is easy to moderate in care, hardy, and thrives in stable, well-maintained aquariums with plenty of swimming space and compatible tankmates.

Care Requirements

• Tank Size: 20 gallons minimum (best in groups of 5+)

• Temperature: 23–28 °C

• pH: 6.5–7.5

• Water Hardness: Soft to moderately hard

• Temperament: Peaceful, schooling, active

• Diet: Omnivore — high-quality flakes, micro pellets, frozen foods, and occasional live foods such as daphnia or brine shrimp

Behavior & Compatibility

Red Line Lizard Tetras are peaceful schooling fish that display their best colors and behavior in groups of 5 or more. They coexist well with:

• Other small to medium peaceful tetras and rasboras

• Corydoras and other gentle bottom dwellers

• Shrimp and snails

Avoid aggressive or very large tankmates that could outcompete or stress them.

Tank Setup

A planted aquarium with open swimming areas, gentle filtration, and moderate lighting is ideal. Floating plants or shaded regions provide security, while a darker substrate accentuates the bright red lateral stripe. Stable water parameters support health, coloration, and active schooling behavior.

A sleek, vibrant tetra with a striking red lateral line—perfect for planted community tanks and lively midwater schools.
