The detail
Zebra danios are small, striped schooling fish from the streams of South Asia, and one of the hardiest aquarium fish there is. They are fast, active and forgiving of beginner mistakes, and they do best in a group of six or more.
- Housing
- 10–20 gal, group of 6 or more
- Tank size
- 2 out of 5 (Small tanks work)
What to weigh
Danios are fast swimmers that need horizontal space, and in small groups they may nip slow, long-finned tankmates. They jump, so a lid is a good idea.
