Hi I have recently added new fish to my freshwater aquarium called coloured Widow Tetras, Same as the black widow tetra, and similar to the bleeding heart tetra but I cant find any information on these fish or the black widow at all, I am looking into breeding these fish but with no information I have no idea what to do. can anybody help me 
As the color is likely artificial it will fade over the next 6 to 12 months and all offspring will be normal Black Widow in color. See the below links for more info..... If it is aPainted fish, it is a fish that has already been cruelly treated.
