Is there some trick to catching one of these? I have caught Tuna,Char,Stringfish, Football Fish, Red Snapper, Cherry Salmon, Rainbow Trout, Goldfish, Koi, and all the rest. I have one fish that is about the same shape in the water as the Dab, Snapper, Olive Flounder, that I have not been able to catch. I tried all the tricks I know, fast set, slow set, etc, nothing has worked. I know the book says catch them when it is snowing or raining, but there has got to be a trick. Help an old man at the sea.
