Temperature: 23 – 27 °C

pH: 5.0 – 7.5

Water Conditions:

• Temperature: Maintain a temperature range of 75°F to 82°F (24°C to 28°C) for the Emperor Tetra.
• pH Level: Aim for a slightly acidic to neutral pH level between 6.0 and 7.5.
• Water Hardness: They prefer moderately soft to moderately hard water with a hardness of 5 to 15 dGH.
• Filtration: Provide efficient filtration to maintain water quality and ensure proper oxygenation.

Tank Mates:

• Peaceful Community Fish: Emperor Tetras are peaceful and can coexist with a variety of fish species, including other peaceful community fish like tetras, rasboras, danios, and small peaceful cichlids.
• Avoid Aggressive or Fin-Nipping Fish: It's best to avoid aggressive or fin-nipping species that may stress or harm the Emperor Tetra.

Feeding Habit:

• Omnivorous Diet: Emperor Tetras have an omnivorous diet. Offer them a variety of high-quality flakes, pellets, and small-sized granules formulated specifically for tropical fish.
• Supplement with Live or Frozen Foods: Provide occasional live or frozen foods such as brine shrimp, bloodworms, or daphnia to supplement their diet and enhance their natural coloration.

Care:

• Hiding Places: Create hiding places in the aquarium using plants, driftwood, and rock formations. Emperor Tetras appreciate having secure retreats and will feel more comfortable in a well-decorated tank.
• Tank Size: A minimum tank size of 20 gallons is recommended for a small group of Emperor Tetras. Larger tanks are necessary for more individuals or if housing with other fish.
• Water Changes: Perform regular partial water changes of about 20% every 1-2 weeks to maintain water quality and promote a healthy environment.
• Behavior: Emperor Tetras are active swimmers and often swim in schools. Keeping them in groups of at least 6 individuals will allow them to display their natural schooling behavior and feel more secure.
