What Fish Go Best With a Bala Shark?

Bala sharks (Balantiocheilos melanopterus) are more closely related to goldfish than true saltwater sharks. Finding a companion for bala sharks requires you to take into account their size and demeanor. Despite growing larger than 8 inches, bala sharks have a peaceful disposition, and need mild -- but large -- tankmates.

  1. Midwater Schooling Fish

    • Bala sharks get along well with other large, midwater schooling fish. Other members of the carp family, like large barbs, have similar care requirements and a similar demeanor. For example, tinfoil barbs (Barbonymus schwanenfeldii) grow large enough to avoid predation but will not bother bala sharks.

    Large Bottom Dwellers

    • Bala sharks can also share a tank with large, bottom-dwelling fish like plecos or cichlids. However, take care, since many fish in this category can be aggressive. Avoid combative cichlids, since bala sharks have trouble holding their own against bullies. Additionally, though most plecos have a reputation as mild-mannered algae eaters, a few large species like the panque may attack bala sharks. Always research a fish thoroughly before placing it in your tank.

    Other Bala Sharks

    • In the wild, bala sharks school for protection. As a result, bala sharks need to be kept in groups or they feel stressed. Always keep bala sharks in groups of at least five fish. In smaller groups, bala sharks may start to pick on other fish due to stress. Within their group, bala sharks will usually establish a hierarchy or pecking order. Since bala sharks grow so large and need to be kept in groups, you need to keep them in tanks of at least 200 gallons.

    What to Avoid

    • Not all fish make suitable tank mates for bala sharks. Avoid any fish small enough to fit in their mouths. This excludes many small schooling fish like smaller tetras and rasboras. Additionally, avoid pugnacious fish. Despite their larger size, bala sharks are pushovers for even moderately aggressive fish. So make sure you keep your bala sharks with large, easygoing fish.
