Appearance

Gold Blue Emperor Tetras have a slender, streamlined body with a beautiful metallic sheen. Depending on the lighting, they display brilliant gold tones along the body with vibrant blue iridescence that gives them their distinctive appearance. Males are generally more colourful and slightly slimmer, while females tend to have a fuller body shape.

  • Bright gold and blue colouration
  • Clear eyes
  • Smooth, undamaged fins
  • Active schooling behaviour
  • A healthy appetite

Natural Habitat

Inpaichthys kerri is native to the slow-moving rivers and tributaries of the Aripuanã River Basin in Brazil. These waters are typically soft, slightly acidic and shaded by dense rainforest vegetation. In the aquarium, they thrive in environments that mimic these natural conditions with plants, driftwood and gentle water movement.


Tank Requirements

Gold Blue Emperor Tetras are best kept in mature, well-maintained aquariums with plenty of swimming space.

Recommended setup:

  • Minimum 60-litre aquarium
  • Keep in groups of at least 6–8 fish
  • Dark substrate to enhance colour
  • Live plants around the edges
  • Driftwood and natural décor
  • Open swimming areas
  • Gentle to moderate water flow
  • Regular partial water changes

A planted aquarium with subdued lighting helps bring out their best colours while providing security.


Behaviour and Temperament

Gold Blue Emperor Tetras are peaceful, active schooling fish that spend most of their time swimming through the middle section of the aquarium.

When kept in good-sized groups, they display confident behaviour, vibrant colours and natural schooling movements. Small groups may become shy or occasionally nip fins, so larger schools are recommended.


Tank Mates

These tetras mix well with other peaceful tropical fish of a similar size.

Suitable tank mates include:

  • Neon Tetras
  • Cardinal Tetras
  • Rummy Nose Tetras
  • Black Neon Tetras
  • Harlequin Rasboras
  • Corydoras
  • Kuhli Loaches
  • Bristlenose Catfish
  • Dwarf Gouramis
  • Peaceful dwarf cichlids, including Rams

Avoid keeping them with:

  • Large aggressive cichlids
  • Fin-nipping species
  • Predatory fish
  • Very large or highly territorial species

Feeding

Gold Blue Emperor Tetras are omnivores and readily accept a wide range of quality foods.

A balanced diet should include:

  • High-quality tropical flakes
  • Small tropical pellets
  • Frozen bloodworms
  • Frozen brine shrimp
  • Daphnia
  • Microworms and other small live foods as occasional treats

Feed once or twice daily, offering only what they can consume within a few minutes.


Water Parameters

Stable water conditions are essential for maintaining vibrant colours and good health.

Ideal parameters:

  • Temperature: 23–28°C
  • pH: 6.0–7.5
  • Ammonia: 0 ppm
  • Nitrite: 0 ppm
  • Nitrate: Below 20 ppm

Consistent maintenance and regular water changes will keep these tetras healthy and active.


Breeding

Gold Blue Emperor Tetras are egg scatterers and can be bred in dedicated breeding aquariums.

Breeding conditions include:

  • Soft, slightly acidic water
  • Fine-leaved plants or spawning mops
  • Dim lighting
  • Separate breeding tank for adults

Adults should be removed after spawning, as they may eat the eggs. The fry require very small foods such as infusoria before progressing to newly hatched brine shrimp.


Common Health Issues

Gold Blue Emperor Tetras are generally hardy when kept in suitable conditions but can develop health issues if water quality declines.

Potential health concerns include:

  • White Spot (Ich)
  • Fin rot
  • Fungal infections
  • Bacterial infections
  • Stress caused by poor water quality or inadequate schooling numbers

Maintaining excellent water quality, keeping them in groups and providing a varied diet will greatly reduce the risk of illness.
