Hey how long will tangs live? I just lost a Purple regal tang that I had for 4 years by June of this year. No real signs of problems and water quailty is near dead perfect. Is this an old age thing. My tank is 125 gallon 125 lbs of live rock. All types of growth both hard and soft corals. The only problem I can see is that my temperature tracks around 79 to 80 degrees. This was a Mediterrian Regal also. I lost a red lip blennie after 4 years. Is this a realistic shelf life?
