Compatibility score
Profile confidence: high
Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
500L
Combined minimum footprint reference for these two species: about 500L (larger active fish often want more length).

Next steps
Concrete changes, not "research more" filler.
- •Bala / silver shark should be kept in a group of at least 5 for best health and behaviour.
- •Denison's / red-line torpedo barb should be kept in a group of at least 6 for best health and behaviour.
- •Bala / silver shark reaches ~35cm: tank length and turning room matter more than the litre number. A tall, short tank of the same volume is not equivalent.
