Zebra Loach tank mates
A 10 cm loach with high-contrast striping that needs company. A group of five shows natural foraging; a solo fish hides permanently.
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 Zebra Loach 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.
The Zebra Loach profile lists Dwarf Gourami as both safe and a recommended pairing. Dwarf Gourami swims in the top zone while Zebra Loach stays in the bottom, so the two will not crowd the same water column.
The Zebra Loach 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. Harlequin Rasbora swims in the middle zone while Zebra Loach stays in the bottom, so the two will not crowd the same water column.
The Zebra Loach 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. Neon Tetra swims in the middle zone while Zebra Loach stays in the bottom, so the two will not crowd the same water column.

Fish to avoid with Zebra Loach
From the unsafe list — predation, aggression, or space rules on this profile.
Oscar reaches 35cm and is flagged predatory. Zebra Loach at 10cm is prey-sized for it. Oscar needs at least 300L, far above the 120L minimum for Zebra Loach. The tank that houses one stresses the other. Oscar is rated aggressive and Zebra Loach is rated peaceful. No community-style planning carries that gap.
Jack Dempsey reaches 25cm and is flagged predatory. Zebra Loach at 10cm is prey-sized for it. Jack Dempsey is rated aggressive and Zebra Loach is rated peaceful. No community-style planning carries that gap.
Green Terror reaches 30cm and is flagged predatory. Zebra Loach at 10cm is prey-sized for it. Green Terror needs at least 300L, far above the 120L minimum for Zebra Loach. The tank that houses one stresses the other. Green Terror is rated aggressive and Zebra Loach is rated peaceful. No community-style planning carries that gap.
Tank size and groups
- Published minimum for Zebra Loach: 120L — group minimum 6 (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: 120L 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.
Filtration & heating
