Hypotheticly theorizing here, but I do believe that *some* bowfin like fish over beef heart, as the fish that I may or may not have smells fish and goes after it(cut up and frozen rock cod I think as it was cheap in fillet form) but doesn't seam to care for beefheart(with seafood mixed for scent)...
Also this supposed bowfin fish is now standing off the green sunfish that I for sure am keeping.. They are legal right?! (lol)
