Same group

Neon Tetra
Paracheirodon innesi
The default midwater school.
A group of six-plus fills the middle of a 20 long so the tank does not look empty.

Cardinal Tetra
Paracheirodon axelrodi
A showier neon that wants better water.
Same schooling job as neons, with a full-body red stripe.

Ember Tetra
Hyphessobrycon amandae
Nano school for a planted 10.
Actually fits a 10-gallon as a group.

Harlequin Rasbora
Trigonostigma heteromorpha
Calm midwater school for a 20 long.
Less nippy than barbs, less fragile than cardinals.

Zebra Danio
Danio rerio
Fast top-water school. Hardy, slightly chaotic.
Tolerates cooler rooms than tetras.

White Cloud Mountain Minnow
Tanichthys albonubes
The honest no-heater school.
Lives in the mid-60s without a heater if the room stays cool.
