trying to identify if ii have a clarkii or sebae

[paul]

i have had a few clarkii's in my tank for awhile now. i'm trying to identify one of them. the fish is dark brown, even the tail. it has a underbite which none of the others have. the tail is also different, it kind of has a trailer on the top section of tail like a surgeonfish has. also it only has two white stripes. lately it has seemed to pair up with one of my ora clarkii's. the ora has now grown larger. i've been looking at pictures online to compare. do you have any ideas or links for me to look at.

also, i have a small clarkii about an inch and half. it has a cool middle line that at the fin the stripe turns towards the rear. also on the tail it has a large white area at the top. is this just from breeding or what.
