What fish can live with Dojo / weather loach?

Use the "Often compatible" lists as a shortlist, not a stocking plan. Always run the pair tool and check the footprint of your actual tank first. Verify behaviour for Dojo / weather loach against your own reading before you buy.

What tank mates should you avoid with Dojo / weather loach?

Avoid Oscar, African Cichlid, Pea Puffer based on size, temperament, or predation risk on file.

What size tank do Dojo / weather loach need for a community?

150L is the planning floor for adult swimming space and bioload headroom. Long-term, a 200L+ tank lets adults use the full footprint without crowding the next species. Footprint, meaning length and front-to-back depth, matters as much as raw volume for active or territorial species.

Best tank mates (on file)

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

Boesemani Rainbowfish Pair check
The Dojo / weather loach profile lists Boesemani Rainbowfish as both safe and a recommended pairing. Boesemani Rainbowfish schools in groups of 6 or more, so plan room for the whole group rather than one fish.
Corydoras Catfish Pair check
The Dojo / weather 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. Corydoras Catfish grows to about 6cm, which is borderline mouth-size for an adult 25cm Dojo / weather loach.
Dwarf Gourami Pair check
The Dojo / weather loach profile lists Dwarf Gourami as both safe and a recommended pairing. Dwarf Gourami grows to about 8cm, which is borderline mouth-size for an adult 25cm Dojo / weather loach.
Neon Tetra Pair check

Risky or situational

From risky tank mates and broad avoid with (excluding “unsafe” below). May work with species-only setups, more water, or mature systems — read the pair page.

German Blue Ram Open pair check
Temperature ranges barely overlap between the two, so one species ends up living at the edge of its comfort window. Run the pair checker before stocking.
Kuhli Loach Open pair check
Marked risky or situational on the profile. Tank length and group size change the outcome more than a temperament label does.
Yoyo Loach Open pair check
Yoyo Loach is rated semi-aggressive, so expect chasing, fin damage, or display behaviour directed at Dojo / weather loach. Run the pair checker before stocking.
Green Terror Open pair check
Green Terror is flagged predatory. Equal-size adults usually coexist, but the moment one is stressed, sick, or smaller after a moult, it becomes prey. Green Terror is rated aggressive, so expect chasing, fin damage, or display behaviour directed at Dojo / weather loach. Run the pair checker before stocking.
Jack Dempsey Open pair check
Jack Dempsey is flagged predatory. Equal-size adults usually coexist, but the moment one is stressed, sick, or smaller after a moult, it becomes prey. Jack Dempsey is rated aggressive, so expect chasing, fin damage, or display behaviour directed at Dojo / weather loach. Run the pair checker before stocking.

Tank size and groups

Published minimum for Dojo / weather loach: 150L — group minimum 5 (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: 160L 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.
