oceansoftheworld:(Photo by JennyHuang)This is a juvenile emperor angelfish (Pomacanthus imperator). The emperor angelfish is a species of marine angelfish. It is a reef-associated fish, native to the Indian and Pacific Oceans .Juveniles are dark blue with electric blue and white rings; adults have yellow and blue stripes, with black around the eyes. The two look completely different and would appear to be a different species to one that does not know about the species. It takes about 24 to 30 months for an emperor angelfish to acquire its adult colouring. They grow to 40 cm (15.75 in) in length.(Source) -- source link
