75 Gallon Tank and Two Different Tangs?

[hoffy]

I have a 75 gallon tank with live rock, two small damsels and a maroon clown. I want to add a Powder Blue Tang and a Purple Tang. Does anyone think this will be a problem? I have read that they need a 100 gallon tank, but isn't that bigger than they would need to have comfortably?

Tangs need a great amount of swim rum, and if you want to keep multiple tangs then I would say you are asking for trouble. I keep multples, a Naso and a Sohal in my 255 gallon tank. I have a friend that keeps 5 in his 450 gallon tank. Powerblue's are prone to ick and purple are aggressive. Both are beautiful tangs. But as I said you are asking for trouble placing these two tangs in a 75 gallon tank. If you are going to do just one, go for the purple. He has a better survival rate than the powderblue.
