The 3" Warrior worm is for all fish species. This is one of the most durable and agile plastics that mimic a real worm. Insane action and durability. Catch dozens of fish on the same worm! Extremely durable and fish truly believe it is the real thing!  Hit these with a little Old Salt Angling scent spray and fish will smack it even harder! 12 per pack! 
(The thickness is of a worm and not a nightcrawler. These are thinner than a crawler)
