   When asked "What is a Blue Tang?" This fish, the Powder Blue Tang, is often given as an example, along with a couple other tangs! Goes to show you how confusing common names can be!

   The Powder Blue Tang is a good example of just how beautiful a tang can be. The color of this fish is a bright light blue with a yellow dorsal fin and caudal peduncle. The face is darker and outlined in white. This is a fairly rare and moderately expensive fish.

Social Behaviors:
   Usually found singly, they form territories in shallow moving water around reef terraces and the edges of reefs. It aggressively defends its territory and therefor whould only be kept singly.

so they can eat their algae!

My Powder Blue Tang (Perry) is awesome. I have had him for about a year and he is about 7 1/2 inches. His tank mates are two Clarkie Clowns and 6 snails. They just underwent a move to a new house and they are enjoying their new dwelling. Perry is just fun to have. His personality is one of a kind. He is the only fish that gets an attitude if you turn on the light too early in the morning, and wake him up. He will hide in the rocks and not come out if you are in the room. Anyhow he is a blast to watch!!

Some of the coolest comments:
If you buy this fish or any marine fish quarantine first to remove the whitespot/itch/crypto as many have this on their bodies when coming from the wild. If you can see tiny white spots on or within the skin treat with a good copper treatment (cupramine seahchem is good). Also while at the petshop make sure he is eating and buy the same food that they are feeding it. Once you get him fat and healthy introduce into a 300 liter+ system with no other established or aggresive tangs.

I'm writing this in the hopes that I might save the lives of a few innocent fish, as well as save you a sizable sum of money. This is a gorgeous fish. Believe me I had my heart set on keeping one. Unfortunately I ended up killing two in the process. These fish are EXTREMELY prone to Ich (white spot), usually don't tolerate other tangs (especially the powder brown), and don't do well in tanks of less than 180 gallons (they are active and like to roam). If you do decide to buy one, avoid specimens that show ANY signs of stress (they don't usually do very well during collection). Look for vivid blue color, active, coherent, and a thick body. Have the store show you that it is eating. Once home, quarantine if possible. If not possible, these fish benefit from a freshwater dip (match PH and temperature, leave fish in for a minimum of 5 minutes, no more than 10, pull out at first signs of stress). This will help kill any hitchhiking parasites. Drip acclimate slowly and leave the lights off for a few days. Maintain high water quality and offer macro algae (brown seaweed). I know people who have kept them successfully, but they've all had to deal with Ich. If you're prepared to give this fish the care and environment it deserves, be my guest, they're a beautiful addition to a tank. If not, please consider a hardier surgeonfish like the Yellow Tang.

I have had my powder blue tang Starfish for 9 years! I had no idea a saltwater fish in captivity would live this long. He is only about four inches long, but so beautiful. He is like a true family pet and I will be sad to see him go. He loves brine shrimp and flakes, and dines on the algae in my tank daily. Truly a beautiful fish.
