To Reef Tank:
Red Pentaceraster Sea Star
Yellow Tang (Zebrasoma flavescens)
Firefish (Nemateleotris magnifica)
Yellow Tangs are what most people think of with a saltwater tank. Brilliant yellow and shaped like a pancake with a nose, these fish swim in great herds off the coast of Hawaii. In captivity, they are aggressive to each other, as the percieved food demand increases. They graze on algae of almost any type, and are a nice colorful and active addition, even if they are swimming in almost any saltwater aquarium you view.
