Tilefish reach about 6 inches or so. They’re reef safe but may eat shrimps & other invertebrates. They do better in a tank with rocks, sand, and open space. They need sand as they will drive into the sand at night or when scared. They do best when kept with others tilefish but shouldn’t be kept with aggressive fish as they do spook very easily. They also need a tight lid because if they are spooked, they will jump out.
