Bluelined Triggerfish
This species is referred to as Bluelined Triggerfish, Blue Triggerfish, Rippled Triggerfish, or Yellowspotted Triggerfish. Juveniles are yellow-bodied and thickly covered with blue lines. A black saddle spot appears between the eyes, at the base of both dorsal fins, and on the caudal peduncle. In an excited state, the fish’s black spots appear to grow until the body is entirely black with pale iridescent blue lines. As adults, the body coloring develops to orange or green. These fish grow to about 22 inches, requiring an aquarium of 200 gallons. They enjoy sandy bottoms, so aquarists may want consider providing a fine or sandy substrate in the aquarium. Aquarists will enjoy watching them blow into the substrate, seeking hidden invertebrates. They are particularly fond of hard-shelled echinoderms and tubeworms. Hence, they are not reef safe. They are best kept with large, aggressive fish in a large aquarium. Although, it is not unusual for this fish to nip at any fish that comes near it. It is also one of the worst species, known for rearranging the tank, including large pieces of rock.
