Both parents spawn in open water and the eggs float at the surface; male and female then stay with the fry for an extended period. No nest is built.
A pair in a large tank.
800 L tank with plants and caves.
Warm water and heavy feeding.
Hundreds to thousands of eggs.
Fry feed on plankton then baby brine shrimp.
One breeding tank for the forest snakehead, drawn to scale from the breeding guide.
Water: 22–28 °C · pH 5–7.5
A plan from the breeding guide and an adult size of 53 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 forest snakehead in numbers.
In total: 3 tanks, about 4,000 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.
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.
