Good fit for your tank?

Good fit for

  • A gentle community of similarly sized fish
  • A planted tank of around 70 litres or more
  • A keeper who wants a calmer alternative to red tetras

Think carefully if

  • Your tankmates are boisterous or large
  • You want strong colour straight away from young fish
  • You can keep only a few fish

A peaceful Brazilian tetra with a soft lemon body and yellow-and-black fins. It is an easy community fish whose colour improves in a well-kept group.

Appearance and Identification

A translucent lemon-yellow body, a bright red upper half of the eye, and an anal fin marked in black and yellow.

The combination of the yellow-and-black anal fin and red eye separates this fish from other pale tetras.

Males are less deep-bodied and slightly smaller, with more intense colour, especially in the dorsal and anal fins.

Provide planted areas with open water. Dark substrate and a varied diet help bring out the yellow.

Behaviour and Tankmates

Very peaceful. Males often display their fins to each other without harm.

Keep a mixed-sex group of at least 8 to 10.

Not territorial, though males display to each other.

Suitable with similarly sized characins, small catfish, and non-predatory small to medium cichlids. Avoid fish large enough to swallow it.

Water Parameters

Temperature
20–28 °C
pH
5–7.5
GH
1–12
Stability importance
Normal

Adaptable to soft and moderately hard water. Keep nitrate low with regular water changes.

Parameter caveat
Most fish sold are farm-bred and more adaptable than wild stock. Acclimate slowly and use the seller's water as a starting point rather than chasing an exact number.

Feeding

Diet types
Insectivore, Omnivore
Feeding frequency
Once or twice daily
Preferred foods
  • Fine micro granules or crushed flakeUse a particle size the fish can swallow whole, and feed only what is eaten within a couple of minutes.
  • Frozen or live daphnia and cyclopsSmall crustaceans add variety and help bring adults into breeding condition.
  • Frozen or newly hatched brine shrimpA good small meat food a few times a week rather than the only food.

An omnivore that takes most small foods.

Regular frozen or live foods noticeably improve colour.

Breeding

Breeding type
Egg Scatterer
Breeding difficulty
Moderate
Brood or egg count
Typically dozens to a few hundred small eggs
Incubation
1 days
Parental care
None
Baby foods
  • Infusoria or parameciumNeeded for the first days after fry become free-swimming, because the fry are very small.
  • Fine powdered fry foodUse sparingly as a supplement, and siphon out anything left uneaten.
  • Newly hatched brine shrimpIntroduce once the fry are large enough to swallow it, usually after several days.
  • MicrowormsA useful next step for fry that are still too small for brine shrimp.

An egg-scattering free spawner with no parental care. Use a separate, dim tank with mature water and a spawning substrate such as mesh, plastic matting, marbles, or fine-leaved plants, then remove adults once eggs appear.
