Open substrate spawner: eggs are laid on a cleaned hard surface, then the wrigglers are moved to pits dug by the parents. Both parents guard the fry for up to 6 weeks, then may spawn again and kill older fry if not removed.
Grow out 6 juveniles and let a pair form; separate the pair if others are harassed.
A 600 L tank with a sponge or gentle filter, flat slate or rocks as spawning surfaces and a tight lid.
Warm, clean water, frequent water changes and protein-rich food.
Up to about 5,000 eggs (reported up to 10,496); large adults can produce ~3,000 fry
Parents move the wrigglers to pits and guard the free-swimming fry; feed newly hatched brine shrimp and crushed flake.
One breeding tank for the jaguar cichlid, drawn to scale from the breeding guide.
Water: 24–30 °C · pH 6–8
A plan from the breeding guide and an adult size of 61 cm. Tank shape is a standard 2 : 1 : 1.2 box, at least 6 adult lengths long. Check each step in the guide above.
A row of tanks on their own stands for breeding the jaguar cichlid in numbers.
In total: 3 tanks, about 3,000 L of water. A litre of water weighs about 1 kg, so check that the floor and rack can take the weight.
Sizes are worked out from the breeding tank in the guide. Tanks fit a standard 120 cm rack when they can; bigger tanks go on their own stands.
Males are larger with pointed dorsal and anal fins and generally more colour; females are smaller and rounder, and breeding females show a stronger crimson tint on the gill cover.
Typical for open substrate spawners
Grow up a group and let a pair choose each other. Give them a flat stone or broad leaf.
The pair cleans the stone and lays rows of eggs. Both guard them.
Wrigglers hatch in 2–4 days and are moved to pits by the parents.
Feed baby brine shrimp several times a day. Parents often herd the fry.
Move fry to a grow-out tank before the parents spawn again.
