Appearance and identification

Unlike clown rasboras, it lacks two large flank blotches; its bold markings are on the tail lobes. Neither should be selected for a tiny tank based on juvenile size.

Same-species behaviour

The source recommends at least six conspecifics; social grouping does not imply continuous tight schooling.

Space requirements

Seriously Fish suggests a 120 × 45 cm base; capacity for a specific adult group is unverified.

Diet and feeding

Offer prepared and live or frozen foods; monitor competition from active feeding.

Compatibility limits

A browsing link or peaceful description does not guarantee compatibility; assess predation, feeding competition, space and water separately.

Aquarium environment

Plant along the margins while retaining open water and an unobstructed swimming lane.
