Best tank mates (on file)

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

Bala / silver shark Pair check
The Tinfoil barb profile lists Bala / silver shark as both safe and a recommended pairing. Bala / silver shark schools in groups of 5 or more, so plan room for the whole group rather than one fish.
Boesemani Rainbowfish Pair check
The Tinfoil barb 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 Tinfoil barb.
Corydoras Catfish Pair check
The Tinfoil barb 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 Tinfoil barb. Corydoras Catfish swims in the bottom zone while Tinfoil barb stays in the middle, so the two will not crowd the same water column.
Denison's / red-line torpedo barb Pair check
The Tinfoil barb profile lists Denison's / red-line torpedo barb as 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. Denison's / red-line torpedo barb grows to about 12cm, which is borderline mouth-size for an adult 35cm Tinfoil barb.
Giant danio Pair check
The Tinfoil barb 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 Tinfoil barb.

Tank size and groups

Published minimum for Tinfoil barb: 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.
Nearest litre hub to this minimum: 300L hub.

Easier alternatives to consider

Conservative beginner-peaceful picks from the library — not replacements for reading, but a shorter on-ramp than this species for a first tank.
