Native to clear, slow-moving waters in Brazil, Ember Tetras (Hyphessobrycon amandae) grow to just 0.8 inches (2 cm), making them perfect for nano tanks. Their brilliant orange-red bodies glow under LED lighting, creating a jewel-like school effect. As beginners, start with subdued lighting to mimic their shaded habitat.​​

Tank Setup for Success

Set up a 10-gallon (38L) tank or larger with dense plants like Java moss or Amazon swords for hiding spots, plus driftwood and leaf litter to replicate their natural environment. Use a gentle sponge filter to avoid strong currents, and add floating plants for security—these reduce stress and encourage natural behaviors. Dark substrates enhance their vivid colors.

Water and Maintenance Basics

Maintain stable parameters: 72–82°F (22–28°C), pH 5.5–7.0, and soft to moderate hardness. Perform 20–30% weekly water changes to keep nitrates low, as these sensitive fish thrive in pristine conditions. Test water regularly with beginner kits—stability matters more than perfection.

Feeding Guide

Omnivores that accept high-quality flakes or micro-pellets, but supplement with live or frozen foods like baby brine shrimp (Artemia nauplii) or daphnia 2–3 times weekly for optimal color and health. Feed small amounts 1–2 times daily to avoid waste—watch them eagerly school at feeding time!

Ideal Tank Mates and Behavior

Peaceful and active, they shine in schools of 6–10+. Pair with similar nano species like chili rasboras, pygmy corydoras, or shrimp, but avoid fin-nippers or large aggressive fish. They rarely breed in community tanks but may scatter eggs in planted setups.

Breeding Tips for Beginners

For fun, try a separate 10-gallon breeding tank with fine-leaved plants or spawning mops, soft acidic water (pH 5.5–6.5), and warmer temps (80–84°F). Condition adults with live foods, then remove them post-spawning to protect eggs. Fry need infusoria or powdered food initially.
