I don't think the pumpkinseed is found there, for fish known in Texas check this list, better yet print it out and try to catch them all.

I think there was a struggle in this one to because the darter's tail was torn up.

It could be even though longears are endangerd here but it is still to small to be sure.I don't think that's a pumpkinseed, looks more like a longear to me...difficult to tell.
