Paul, i caught a dink the other day in 90+ degree waters (surface temp), and by dink i mean MAYBE 9 inches. Anyways, of all the other fish i caught that day, this was the only one with red lips. What's interesting was it wasn't just red but bloody. i could literally wipe my thumb over his top lip and have blood on my thumb. and no, it wasn't from having a hook in his mouth cause i hooked him through the thinnest of tissue on the side of his mouth. What do you make of that? what theories does this debunk? if at all? it definitely occurs in the south
