The character of Tails is portrayed as a very sweet-natured[10] and humble fox[11] who, before he met Sonic, was often picked on because of his twin tails. Sonic, however, saw Tails' special talents and cheered him on, causing the fox to have some admiration towards the blue hero.[12] As a longtime friend,[10] he admires Sonic[13] and dreams of being just like him.[14] Though he lacks much courage,[12] he wants to prove that he can be counted on, and has fought Dr. Eggman and his robots without the aid of Sonic before.[15] He loves mint candy,[16] tinkering with machines, and flying mechas.[12] Despite overcoming most of his fears and becoming very bold, Tails remains keraunophobic.

I would prefer a female play this role because they can do the kid voice better in my opinion, but go ahead if you think you're up for the challenge!
