Setup

A 150 L tank with a sponge or gentle filter, flat slate or rocks as spawning surfaces and a tight lid.

What starts it

Warm, clean water, frequent water changes and protein-rich food.

Eggs

Hundreds of eggs per spawning.

Raising the fry

Parents move the wrigglers to pits and guard the free-swimming fry; feed newly hatched brine shrimp and crushed flake.

Common mistakes

The story of the blue-spotted acara

A Central American acara from Panama and Costa Rica, named for the blue spots on its flanks. It grows larger than its "small acara" reputation suggests, up to about 19.5 cm SL.

Austrian zoologist Rudolf Kner described this acara in 1863, originally in Acara. It is one of the few acaras found in Central America, living on both slopes of Panama and Costa Rica. Its many blue-white spots give the species its name.

First described by Rudolf Kner in 1863.

  • Its body has many small blue spots.
  • It is a substrate spawner.
  • It reaches about 15 cm.

12 facts checked with sources

  • Scientific name

    Valid name (Kner, 1863); formerly in Aequidens. Not on Seriously Fish. Not the same fish as the common "blue acara" (Andinoacara pulcher); shops sometimes mix the names.

  • Familycorrected

    Legacy has no family field.

    FishBase: Andinoacara coeruleopunctatus summary
  • Sizecorrected

    Current FishBase max is 19.5 cm SL (a newer reference); Wikipedia quotes an older FishBase figure of 14.5 cm TL. Larger well-sourced figure used, so plan for a fish of 15-20 cm. No Seriously Fish profile.

  • Group size

    Wild fish form small groups, but no source gives an aquarium minimum.

    FishBase: Andinoacara coeruleopunctatus summary
  • Swimming level

    Benthopelagic; FishBase notes it stays near the bottom, so lower-middle.

  • Where it livescorrected

    Legacy says "Central and northern South America"; sources give Central America only.

    FishBase: Andinoacara coeruleopunctatus summary
  • Breeding

    Legacy "pairs guard eggs on a flat rock" agrees in substance.

    FishBase: Andinoacara coeruleopunctatus summary
  • Eggs and young

    Legacy 150-300 fits "hundreds"; no hatch time found.

    FishBase: Andinoacara coeruleopunctatus summary
  • Storycorrected

    Legacy said Central and northern South America and "small"; both corrected. Blue spangles are implied by the name (coeruleopunctatus = blue-spotted) but not described in a fetched source.
