thx for replying bro's
marlin brando started eating but only live FW ghost shrimp
cant find one small enough so i had to mutilate the shrimp b4 feeding, and it work wonders ... even arc hawkfish is feeding now
will try frozen + pieces of shrimp tomorrow
BTW i have one harlequin shrimp, n it is spared, even fu man chu does not bother my harlequin
