Allow plenty of room, use a very secure lid and fit strong filtration. Predators produce a lot of waste, and many are strong jumpers.
A predator that spends much of its time watching and waiting for prey.
Usually best alone, or in a very large tank with others of its size.
Many are intolerant of their own kind.
It will eat any fish that fits in its mouth, so keep it with fish too big to swallow, or alone. It is likely to eat shrimp.
Fairly tolerant of different water, if it is clean and stable. Keep the temperature steady.
A nocturnal predator that eats fish, crustaceans and worms. Feed sinking pellets with frozen fish, prawns and earthworms.
Feed small amounts, and remove anything left after a few minutes.
An egg scatterer with no parental care. Adults eat eggs and fry, so use a separate tank with fine plants, moss or mesh on the bottom, and remove the adults after spawning. The fry need very small foods at first.
