Rummy Nose Tetra tank mates
The school-quality benchmark. Red noses mean the water and stress level are right. Pale noses mean something is wrong before the test kit shows it.
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 Rummy Nose Tetra profile lists Angelfish as both safe and a recommended pairing. Angelfish grows bigger than Rummy Nose Tetra (20cm vs 5cm). Stock the Rummy Nose Tetra group large enough to outnumber the Angelfish, or the smaller fish ends up bullied or off food.
The Rummy Nose Tetra profile lists Cardinal Tetra as both safe and a recommended pairing. Cardinal Tetra schools in groups of 6 or more, so plan room for the whole group rather than one fish.
The Rummy Nose Tetra 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 Rummy Nose Tetra stays in the middle, so the two will not crowd the same water column.
The Rummy Nose Tetra profile lists Dwarf Gourami as both safe and a recommended pairing. Dwarf Gourami is a peaceful beginner-care species with a 60L minimum. Run the pair checker for your specific tank before stocking.
The Rummy Nose Tetra profile lists German Blue Ram as both safe and a recommended pairing. German Blue Ram is a peaceful intermediate-care species with a 80L minimum. Run the pair checker for your specific tank before stocking.

Fish to avoid with Rummy Nose Tetra
From the unsafe list — predation, aggression, or space rules on this profile.
Oscar reaches 35cm and is flagged predatory. Rummy Nose Tetra at 5cm is prey-sized for it. Oscar needs at least 300L, far above the 80L minimum for Rummy Nose Tetra. The tank that houses one stresses the other. Oscar is rated aggressive and Rummy Nose Tetra is rated peaceful. No community-style planning carries that gap.
Jack Dempsey reaches 25cm and is flagged predatory. Rummy Nose Tetra at 5cm is prey-sized for it. Jack Dempsey needs at least 200L, far above the 80L minimum for Rummy Nose Tetra. The tank that houses one stresses the other. Jack Dempsey is rated aggressive and Rummy Nose Tetra is rated peaceful. No community-style planning carries that gap.
Tiger Barb conflicts with Rummy Nose Tetra on temperament, predation, or footprint. The juvenile size in a shop tank is not the figure that matters here.
Tank size and groups
- Published minimum for Rummy Nose Tetra: 80L — group minimum 8 (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: 80L 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.
Plan before you buy
Pair checks for every mix, then multi-species stocking in the builder.
