Pearl Gourami tank mates
Larger than honey or dwarf gourami at 12 cm, and calmer than most. Tall body wants a tall planted tank with surface plants and quiet mid-water company.
Lists below are built from this species record (safest, best with, risky, unsafe) — each link opens a pair-level check, not a guarantee.
Best tank mates (on file)
Merged from conservative safest and best with fields — de-duplicated by species.
The Pearl Gourami profile lists Angelfish as both safe and a recommended pairing. Angelfish is a semi-aggressive intermediate-care species with a 150L minimum. Run the pair checker for your specific tank before stocking.
The Pearl 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.
The Pearl 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 Pearl Gourami stays in the top, so the two will not crowd the same water column.
The Pearl 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.
The Pearl 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 Pearl Gourami
From the unsafe list — predation, aggression, or space rules on this profile.
Tiger Barb conflicts with Pearl Gourami on temperament, predation, or footprint. The juvenile size in a shop tank is not the figure that matters here.
Betta conflicts with Pearl Gourami on temperament, predation, or footprint. The juvenile size in a shop tank is not the figure that matters here.
Oscar reaches 35cm and is flagged predatory. Pearl Gourami at 12cm is prey-sized for it. Oscar needs at least 300L, far above the 100L minimum for Pearl Gourami. The tank that houses one stresses the other. Oscar is rated aggressive and Pearl Gourami is rated peaceful. No community-style planning carries that gap.
Tank size and groups
- Published minimum for Pearl Gourami: 100L — 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: 100L hub.
Plan before you buy
Pair checks for every mix, then multi-species stocking in the builder.
