Breeding the angelfish

Females lay up to about 1,000 eggs; at 28°C the first larvae hatch after about 2 days, and larvae start feeding on live food 4-5 days after hatching.

Step by step

Pairing

Raise 6-8 young fish together and let pairs form. Pairs often claim a spot on their own.

Breeding tank

A 30-55 gallon (110-200 L) tall tank, 27-29 C, soft water, with a slate, leaf or PVC pipe as spawning site.

What starts it

Warm water, a water change with soft water and good food. Pairs clean a flat surface.

Eggs and young

100-500 eggs; hatch in 2-3 days, free swim at 5-7 days.

Raising the fry

Feed baby brine shrimp from day 5, and then crushed flake and microworms. Remove eggs for artificial hatching if parents eat them.

Common mistakes
  • Taking too long to separate a bad pair
  • Water that is too hard for hatching
  • Overfeeding and fouling the fry tank

Male or female

Very hard to sex; males have a smaller, pointed genital papilla, usually only visible when spawning.

Can I breed it in my tank?

  • Good for a first breeding project.

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.

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