Want to add a powder blue tang to my 125 gallon tank. Tank mates include anthias, pair of clowns, blue damsel, cardinal, cleaner shrimp and hermit crab. Compatability should be no problem. Everone I talk to says Power Blues are very hard to keep and not to do it. Are they really that tough to keep, If water quality is good? I was also told not to try Anthias but todate they are doing fine? I would appriciate advise from anyone out there that has a powder blue and what your experience has been, especially regarding ick.
