Green
Variety
A green guppy is selected for green body or fin coloration, often produced by iridescence layered over yellow, blue, or darker pigment. True green can be harder to fix than red or blue, so many green lines show turquoise, olive, emerald, or metallic flashes depending on light and angle. The color may appear in delta, mosaic, Moscow, or multicolor backgrounds.
Keeping green guppies is not different from keeping other fancy guppies, but breeding consistent color takes careful observation. A fish that looks green under shop lighting may shift toward blue or yellow in another tank, so breeders judge mature males under steady conditions and keep notes on parentage. Healthy females, strong fry growth, and clean finnage matter because weak structure can hide behind an eye-catching sheen.
