To be honest i now think we are getting into the realms of guessing, one one side we have Tony saying Alans fish is roach/rudd and then we have Mike saying it is roach/bream, i said earlier that i hadn't caught any big rudd so i couldn't comment on the roach/rudd idea...but i think the way that Alan is holding the fish makes it difficult to judge the positioning of the fins and if that is what Tony is basing his statement on then i'm not so sure. Alan seems to pushing out the front of the fish if you look really close, it isn't being held straight at the camera, this in my opinion makes it difficult to acertain the fins positioning.
I may be wrong and i will certainly hold my hands out if i am but i still think they are roach/bream.
