Zebra Loach tank mates

If the yoyo loach is the gang, the zebra is the housetrained cousin: the same snail appetite in a 10 cm fish that stays peaceful in a 120L community. It keeps one botiid non-negotiable — six of its own kind, or it hides and you own striped gravel.

Common mistakeKeeping one or two zebra loaches in a large community is how people decide the species is shy and dull. Singles hide, skip the queue behaviour, and never show the active foraging visible in a proper group. Plan for six on smooth sand or rounded gravel in roughly 120 litres or more. A pair is not a starter pack for this loach.

Usually safer companions

Conservative shortlist from this profile. Open a pair page before you buy.

  • Dwarf GouramiPair check

    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.

  • Harlequin RasboraPair check

    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.

  • Neon TetraPair check

    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.

Risky or situational

May work with more water, a mature system, or a species-only setup. Read the pair page before you experiment.
