The Yellow Line Snapper is a gorgeous snapper fish with a light blue body. It features a couple of white and yellow horizontal stripes running down its mostly blue body and a spotless white belly. Since they are very active, they require a lot of swimming space. The Yellow Line Snapper is a quick carnivorous fish and can feast on a vitamin-rich diet of mysis shrimp, brine shrimp and meaty frozen foods. As it becomes an adult, it can be fed small chunks of fresh sea food.
