anyone remmember the tulip eels that used to be a dime a dozen back 20-30 years ago,you use to find them in any pet store,they use to stick straight up in the tank with there head facing the top of the tank and wait for a fish to swim by,and then strike so fast you could not even see it,one of the fastest strikes of any fish,they got big to over 20 inches and inch thick. these still for sale in the hobby? anyone keep?
