Naso Tang
Tangs are commonly referred to as surgeon fish due to having a sharp spine that looks like a "scalpel" at the base of their caudal (tail) fin that is used for protection, use caution when handling. They should not be kept with fish that look similar, like other tangs. However, they should be peaceful towards most other tank mates. The Naso Tang will grow to be over a foot in size, so they will need substantial swimming room. Full grown adults of this tang will need around 250 gallons; however, you can get away with smaller aquariums when they are juveniles. The Naso Tang goes through a drastic color morph from juvenile to adulthood. Juveniles will be a dark gray with a blue strip outlining the dorsal fin and an orange on outlining the anal fin. As this tang matures the body will become more grey-reddish and the tail will become a lyre shape. Their face will develop distinct markings and colors of yellow, black and orange.
