I have tried rainbow roe, boraxed pink, and yellow, and tried plain natural, it worked to some extent, but they like waxies more. They might want to hit more of that orange color if they are feeding on shrimp, but would of like it first ice, found the buggers hard on 10 foe water flats, eating on tulibee eggs. They would of went nuts over natural roe, gauranteed, but then again, never know. Only thing is to try it.
