Hardy, colorful, breed readily in home aquariums.

Labyrinth fish — peaceful females and community males need space.

Cleanup crew: catfish, loaches and shrimp that forage on the substrate.

Intelligent and territorial — from dwarf species to large Central American stock.

Coldwater species that outgrow most community tanks.
