Of course. When you find a shiny and battle it, stars pop out of it (appart from the different color)
SO for example, if your on tall frass running around like a madman, and a battle pops up and its shiny, youll see the pokemon appear as normal, from the left of the screen to the right of it, and when it stops and it shows perfectly, youll see stars pop out and youll see that the color is different from the normal color.
It doesnt have anything else. Thats all there is to it. Luck and dedication to find it.
