What size tank do Bala / silver shark need for a community?

500L is the planning floor for adult swimming space and bioload headroom. Long-term, a 600L+ tank lets adults use the full footprint without crowding the next species. Footprint, meaning length and front-to-back depth, matters as much as raw volume for active or territorial species.

Best tank mates (on file)

Merged from conservative safest and best with fields — de-duplicated by species.

Boesemani Rainbowfish Pair check
The Bala / silver shark profile lists Boesemani Rainbowfish as both safe and a recommended pairing. Boesemani Rainbowfish schools in groups of 6 or more, so plan room for the whole group rather than one fish. Boesemani Rainbowfish grows to about 11cm, which is borderline mouth-size for an adult 35cm Bala / silver shark.
Corydoras Catfish Pair check
The Bala / silver shark profile lists Corydoras Catfish as both safe and a recommended pairing. Corydoras Catfish schools in groups of 6 or more, so plan room for the whole group rather than one fish. Corydoras Catfish grows to about 6cm, which is borderline mouth-size for an adult 35cm Bala / silver shark. Corydoras Catfish swims in the bottom zone while Bala / silver shark stays in the middle, so the two will not crowd the same water column.
Denison's / red-line torpedo barb Pair check
The Bala / silver shark profile lists Denison's / red-line torpedo barb as both safe and a recommended pairing. Denison's / red-line torpedo barb schools in groups of 6 or more, so plan room for the whole group rather than one fish.

Giant danio Pair check
The Bala / silver shark profile lists Giant danio as both safe and a recommended pairing. Giant danio schools in groups of 6 or more, so plan room for the whole group rather than one fish. Giant danio grows to about 11cm, which is borderline mouth-size for an adult 35cm Bala / silver shark.
Tinfoil barb Pair check
The Bala / silver shark profile lists Tinfoil barb as a recommended pairing. Tinfoil barb schools in groups of 5 or more, so plan room for the whole group rather than one fish.

Risky or situational

From risky tank mates and broad avoid with (excluding “unsafe” below). May work with species-only setups, more water, or mature systems — read the pair page.

Neon Tetra Open pair check
Marked risky or situational on the profile. Tank length and group size change the outcome more than a temperament label does.
Dwarf Gourami Open pair check
Marked risky or situational on the profile. Tank length and group size change the outcome more than a temperament label does.
Betta Open pair check
Betta is rated semi-aggressive, so expect chasing, fin damage, or display behaviour directed at Bala / silver shark. Run the pair checker before stocking.

Tank size and groups

Published minimum for Bala / silver shark: 500L — group minimum 5 (schooling).
Compatibility changes when the tank is too short for turning, too little for a real school, or too warm for one species and not the other — that is why pair checks include tank context, not only temperament.

Easier alternatives to consider
