Rarely bred in aquaria and not achieved by hobbyists in any documented way. In the wild it spawns in the rainy season, scattering eggs a few at a time among dense plants; no nest is built.
Group of adults.
Large tank.
Cooling.
Females lay about 100-300 eggs over a few days; eggs hatch in 3-4 days and fry swim freely about 3 days later.
Brine shrimp.
One breeding tank for the senegal bichir, drawn to scale from the breeding guide.
Water: 24–28 °C · pH 6–8
A plan from the breeding guide and an adult size of 50 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 senegal bichir in numbers.
In total: 3 tanks, about 2,700 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 have a thicker, broader anal fin than females; females are generally larger.
Typical for egg scatterers
Feed live or frozen food twice a day. Keep males and females apart if you can.
Eggs are scattered over mops or fine plants, often at first light. Remove the parents straight after.
Most eggs hatch in 1–2 days. Keep the tank dim and remove white (fungused) eggs.
Fry use up the yolk and start swimming. Feed infusoria or liquid fry food several times a day.
Switch to newly hatched brine shrimp or microworms. Start small, daily water changes.
Add finely crushed flake. Sort fry by size so the big ones don't eat the small ones.
Most small fish reach about 2 cm in 2–3 months and can join the main tank.
