Does anyone know if these two would ever be able to mate if they are in the same tank? cause I got 4 Zebras and 3 Rosies and they seem to get along very well! they also seem to be very active simming in groups!

No, they won't crossbreed. Rosy Reds are coldwater fish, although they can survive warmer temperatures they won't usually spawn if the temp is over 75 degrees. Danio's are the opposite, they are tropical fish that can survive cooler temperatures, but they won't usually spawn in temps below 76 degrees.
