i added a red devil to my tank 2 days ago, at the juvenile stage, red devil is kind of timid, it gets chased by smaller salvini, pink convict, and bigger red texas(look just like ur carpintis). This red devil was most dominant in the petstore. First time i visit the store, was labeled as "red devil", most them were like your color, whitish. Second time, was label as flamingo, most of them were bright red. The time i pick it up was unlabeled, they didn't know what it was, so i call it red devil.
