The Powder Blue Tang: An Iconic Beauty Demanding Exceptional Care
Ben, I know that these tangs are hard to keep, But you should check your care and tank systems. I have a Powder Blue tang that has been in a 30 gal. tank with clownfish and a Potters Angel for at least 2 years. If you don't have inverts and it only a fish tank try adding some copper, I use coppersafe and haven't seen a white spot since I got him two years ago. I know that my tank is small for a tang but this fish is beautiful and fat. I need to set up my 150 and give it some more room, but so far so good. Try the copper and good luck. It works, just keep in mind you can't keep inverts with copper. Steve
Also known as the blue tang or blue hippo tang, these fish .
The Blue or Hippo Tang, Paracanthurus hepatus, is another surgeonfish that needs a lot of room to swim! They need 180 gallons, lots of strong water movement, plenty of veggies and appropriate tank mates. They will become quite belligerent in smaller tanks and will go after other tangs and fish if they feel crowded. They are one of the easier tangs to care for, aside from being the most popular fish sought after by new saltwater aquarists due to the movie Finding Nemo. Sadly, newbies quickly find that their 55 gallon tank is not going to cut it, as the Blue Hippo Tang will grow to 12," besides producing a lot of waste. Their need, like other tangs, to swim very quickly and aggressively means a 6 foot tank is minimum.
Be prepared to spend some serious jack on this fish though
