The Purple Firefish, a.k.a. Decorated Firefish, is a magnificent little fish that's perfect for reef tanks. These fish have a light lavender colored body with purple markings on their face and towards their tailfin, along with dark red and purple colored fins. The Purple Firefish also has an elongated first dorsal spine that "jumps" up and down. These little fish have lots of personality and should be kept in a tank with lots of rockwork. The Purple Firefish likes lots of crevices, caves, and overhangs where they can "hang" in place. These fish prefer to be kept in pairs and do well in the home aquarium. They are great for reef tanks and will accept most fish foods. These fish are also jumpers, so precautions should be taken to secure openings at the top of the aquarium.The Dartfish family of fish are majestic little fish with an elongated body.
