Blue Line Snapper

About this fish

Blue Line Snapper is a marine fish sold under the scientific name Lutjanus kasmira. In practice, it’s a predatory reef-adjacent “finisher” species for experienced hobbyists who can provide a larger, mature marine setup and feed a meaty diet. Because it’s a snapper, it’s typically kept for its active behavior and long-term presence rather than for a community tank with small, edible tankmates.

Features:

• Marine, carnivorous snapper known for strong predatory feeding behavior
• Best for larger aquariums where swimming space can support its activity as it grows
• Often becomes territorial around feeding times, so tankmates should be chosen carefully
• Generally not considered reef-safe due to predation on small invertebrates
• Responds well to consistent feeding of appropriately sized meaty foods
