Breeding the tapajos red head eartheater

Larvophilous biparental mouthbrooder: the pair spawns on a stone like an open spawner, and after about 2-3 days the larvae are taken into the mouth; both parents share brood care.

Step by step

Pairing

Keep a group of 6 and let a pair form, or one male with several females.

Breeding tank

A 350 L tank with a sponge or gentle filter, fine sand to sift, a few rocks and open swimming space.

What starts it

Clean warm water, big regular water changes and varied protein foods.

Eggs and young

Eggs hatch after about 72 hours and the fry are free-swimming at 8-11 days. No egg count found.

Raising the fry

The brooding parent holds eggs and fry, releasing them at about 1 cm; feed newly hatched brine shrimp.

Common mistakes
  • Coarse or sharp substrate
  • Stressing the brooding fish
  • Infrequent water changes

Male or female

Both sexes develop the red-orange head from sexual maturity (about 8-10 cm SL). Males are more intensely coloured, slightly larger and have longer fin extensions; some dominant males develop a nuchal hump.

Can I breed it in my tank?

  • Takes some experience.

Day-by-day plan

Typical for mouthbrooders

  1. 21 days beforeGroup and condition

    Usually one male with several females. Feed high-quality food.

  2. Day 0Spawning

    The female takes the eggs into her mouth and stops eating.

  3. Day 21Release

    After about 3 weeks the female releases fully formed fry. Many breeders move her to a quiet tank first.

  4. Day 21First food

    Fry eat crushed flake and baby brine shrimp straight away.

  5. Day 90Grow-out

    Fry are a few centimetres long after about 3 months.

A general guide for this breeding type. Days change with temperature and species.

Stage 1 of 5Group and condition

Usually one male with several females. Feed high-quality food.

Simulator: try it yourself

Set up a virtual breeding tank and see what would likely happen.

No spawning
  • Without live or frozen food the parents aren't in breeding condition.
