Diet & Nutrition: Scissortails will generally eat all kinds of live, fresh, and flake foods. 

Breeding & Spawning: Scissortails are egg-scatterers that are relatively easy to breed. For best fry yield, a separate breeding tank is recommended, and should be fitted with either a mesh for the eggs to fall through, or spawning mats. Fill the tank about half full of water that is slightly acidic (6.0-6.5) and at a temperature of 77 to 82 °F (25-28°C). Lighting should be minimal, and filtration should be a sponge type filter.

Gender: Sexual differences in Scissortails are not readily discernible. Males are usually more slender and smaller overall than the female. When ready to spawn, the males will display more robust colors. Females are generally larger and rounder in the belly, particularly when viewed from above.
