Scissortail Rasbora tank mates

A large fast-moving schooler at 15 cm that needs real swim length. Often bought as a starter fish; grows out of small tanks within a year.

Common mistakeKeeping two scissortails in a 60L is how keepers invent pacing, nervous fish that never settle. They need forward run and a real school. Plan 150L-class length with six or more — a short nano pair is the wrong shape for this species.
