Breeding the red-spotted copeina

Lays its eggs in a shallow pit the male digs in the sand; the male fans and guards the eggs and then the fry until they swim freely. It does not spawn above the water like the splash tetra.

Step by step

Pairing

Keep a pair or group; the male leaps with the female to lay eggs on leaves above the water.

Breeding tank

A tank with fine sand and soft, slightly acidic water.

What starts it

Warm soft water and live food; males guard and splash the eggs.

Eggs and young

Eggs hatch in about 24 hours; FishBase's model uses a fecundity of about 100 eggs.

Raising the fry

After 3 days the male splashes eggs with water; fry fall into the water and eat infusoria then brine shrimp.

Common mistakes
  • No lid or overhang
  • Hard water
  • Disturbing the male

Male or female

Males are more intensely coloured than females and tend to develop extended fins.

Can I breed it in my tank?

  • Takes some experience.

Day-by-day plan

Typical for open substrate spawners

  1. 21 days beforeLet a pair form

    Grow up a group and let a pair choose each other. Give them a flat stone or broad leaf.

  2. Day 0Spawning

    The pair cleans the stone and lays rows of eggs. Both guard them.

  3. Day 3Eggs hatch

    Wrigglers hatch in 2–4 days and are moved to pits by the parents.

  4. Day 7Free swimming

    Feed baby brine shrimp several times a day. Parents often herd the fry.

  5. Day 42Grow-out

    Move fry to a grow-out tank before the parents spawn again.

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

Simulator: guided

Stage 1 of 5Let a pair form

Grow up a group and let a pair choose each other. Give them a flat stone or broad leaf.

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.
