Compatibility brief
Can Cherry Barb live with Otocinclus?
Often a workable match in a suitable, well-run tank. Still verify behaviour in your setup.
Compatibility score

Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
60L
Combined minimum footprint reference for these two species: about 60L (larger active fish often want more length).
Assessment details
Known compatible pairing
A staple algae-crew pairing. The only caveat is identity: shop 'otos' are usually O. vittatus or O. macrospilus sold under the wrong name — care is the same, but buy plump, settled fish and feed them properly.
Compatible temperaments
Both Cherry Barb and Otocinclus share a peaceful temperament.
Compatible temperature range
Both fish can comfortably share similar water temperatures.

Individual fish vary in personality. Fishori uses conservative hobby rules. Observe any new introduction closely, feed thoughtfully, and keep a quarantine or backup plan. This is not veterinary advice.
Profile data confidence: high. Checked against several solid care sources that mostly agree. At least one species here has common trade-name ambiguity.
