thanks for the input guys! I'll have to work tomorrow, but on Sunday I'll check out your ideas and then tell you which species it could be as soon as I have done my research...
The first is definately a darter but to be honest Im not going to take the couple of hours searching for the answer.....but I will lead you to a good reference book the Petersons Field guide to freshwater fishes, which is a cheap book if bought online and gives good descriptions to look the fish up with.
