um,not to sound dumb but what the heck is nori anyway?I looked it up on ebay and got nothing but womens pants.I really dont think it matters if its roasted or not I dont think fish will eat the pants
I have feed fish seaweed before.Its dry roasted not roasted.I cant imagine that if it was roasted that it would cause any harm.Dry roasted,like they do peanuts and such,as long as there are no additives.
