concerning the 'thin man' since you both asked, i don't know positively that that's a male...just an educated guess. my female yt's tails come to a rather blunt point at the tip. the males tails come to a much finer point as in that pic. also, around the vent, it just appeared more male to me. couple that w/ they always seem to say it's a female and you have the criterion of my post. i do think that's a male...dannio
