Best tank mates (on file)

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

Cherry Barb Pair check
The Dwarf Gourami profile lists Cherry Barb as both safe and a recommended pairing. Cherry Barb schools in groups of 6 or more, so plan room for the whole group rather than one fish.
Corydoras Catfish Pair check
The Dwarf Gourami 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 swims in the bottom zone while Dwarf Gourami stays in the top, so the two will not crowd the same water column.
Guppy Pair check
The Dwarf Gourami profile lists Guppy as both safe and a recommended pairing. Guppy is a peaceful beginner-care species with a 40L minimum. Run the pair checker for your specific tank before stocking.
Harlequin Rasbora Pair check
The Dwarf Gourami profile lists Harlequin Rasbora as both safe and a recommended pairing. Harlequin Rasbora schools in groups of 6 or more, so plan room for the whole group rather than one fish.
Neon Tetra Pair check
The Dwarf Gourami profile lists Neon Tetra as both safe and a recommended pairing. Neon Tetra schools in groups of 6 or more, so plan room for the whole group rather than one fish.

Fish to avoid with Dwarf Gourami

From the unsafe list — predation, aggression, or space rules on this profile.

Tiger Barb See why (pair)
Tiger Barb conflicts with Dwarf Gourami on temperament, predation, or footprint. The juvenile size in a shop tank is not the figure that matters here.
Betta See why (pair)
Betta conflicts with Dwarf Gourami on temperament, predation, or footprint. The juvenile size in a shop tank is not the figure that matters here.
Oscar See why (pair)
Oscar reaches 35cm and is flagged predatory. Dwarf Gourami at 8cm is prey-sized for it. Oscar needs at least 300L, far above the 60L minimum for Dwarf Gourami. The tank that houses one stresses the other. Oscar is rated aggressive and Dwarf Gourami is rated peaceful. No community-style planning carries that gap.

Tank size and groups

Published minimum for Dwarf Gourami: 60L — group minimum 1 .
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: 60L hub.
