About this fish
Rainbow Shark is an active, peaceful schooling fish whose colours intensify with age and in a group. It prefers neutral-to-hard water and plenty of open swimming space.
Care tips
- Keep 6+ — colour and confidence build in a shoal (and with mature males).
- Neutral to slightly alkaline, harder water suits them well.
- Give long open swimming lanes; they're fast, active swimmers.
