Blue Emperor Tetra: A Regal and Peaceful Addition to Aquariums

The Blue Emperor Tetra (Inpaichthys kerri), also known as the Kerri Tetra, is a stunning freshwater fish celebrated for its iridescent blue body and graceful swimming. These peaceful schooling fish are perfect for community aquariums, offering a touch of elegance and vibrancy. Their hardy nature makes them a favourite for both beginners and experienced aquarists.

Caring for Blue Emperor Tetras

Blue Emperor Tetras thrive in tanks of at least 60 liters, providing plenty of open swimming areas alongside planted sections for cover. Maintain water temperatures between 23°C and 27°C, with a pH range of 5.5–7.5. A darker substrate and subdued lighting enhance their shimmering blue tones. Regular water changes and efficient filtration help maintain the clean, stable water conditions they require.

Tank Mates for Kerri Tetras

These peaceful fish are ideal for community tanks and get along well with other small, non-aggressive species such as Neon Tetras, Harlequin Rasboras, and Corydoras. To encourage natural schooling behaviour, keep them in groups of six or more. Avoid housing them with larger or aggressive fish that might intimidate or harm them.

Feeding Blue Emperor Tetras

Blue Emperor Tetras are omnivores and thrive on a varied diet. Provide high-quality flakes or micro-pellets as their main food, supplemented with live or frozen foods like brine shrimp, daphnia, and bloodworms. Adding occasional blanched vegetables, such as spinach or zucchini, supports their health and helps maintain their vivid colours.

Breeding Kerri Tetras

Breeding Blue Emperor Tetras is relatively simple in a dedicated breeding setup. Use a tank with soft, slightly acidic water and fine-leaved plants or spawning mops for egg-laying. Males display brighter colours during courtship to attract females. Once eggs are laid, remove the adults to protect the eggs. Fry hatch within 24–36 hours and can be fed infusoria or finely crushed fry food until they grow larger.
