Care caveats
- notesActive schooling danio; pearly version of the zebra danio with the same swimming-room demands.
- caveatKeep a group of 6 or more; without a group pearl danios stress and redirect activity onto tankmates.
- caveatActive swimmer that needs real tank length, not just gallons — short or nano tanks waste their natural shoaling behavior.
- caveatCan stress slow, shy, or long-finned tankmates with constant chasing; avoid pairing with bettas, gouramis, or fancy guppies.
- caveatBest in mid-to-large planted community tanks with open swimming space and similarly active or unflappable tankmates.
