Bala / silver shark tank mates

Grows to 35 cm and needs a school. Juvenile 5 cm 'sharks' are irresistible in shops. The adult fish needs 500L or more and eats small fish.

Common mistakeBuying three cute bala sharks for a 100L community is the classic outgrow-and-eat story. Adults push toward 35 cm, need a huge footprint, and will take nano fish once the mouth catches up. This is a public-aquarium-scale school fish, not a silver tetra for a living-room kit.
