hi, I just wanted to know if my chaos have to be hero or dark to mate?,because in my hero garden one of the two aren't hero,and when I feed them both heart food my hero chao grows flowers around him but not the other one

A chao needs to be a adult (this means it needs to be a hero, a dark, or a nurtal chao to breed.) if you feed i child chao a heart fruit and it evoles into to adult it should want to breed right away.
