The photo shows a female of Nile tilapia, Oreochromis niloticus while incubating freshly fertilized eggs. The color of incubated eggs indicates the early age of embryos which could be hours or 1-2 days depending on water temperature. The pigmentation of embryos will follow this stage. Sometimes freshly fertilized eggs are called green eggs.
