Hey fish people. In the far.. near.. future I'm going to convert my 75 gallon african cichlid tank to a sw tank. I've had a tall 30 gal s.w. tank in the past, and have been out of the s.w. hobby for a few years now. My two favorite fish are the Powder Blue Tang and the Humu Picaso Triggerfish. Would these to be ok in a 75 gallon? Also I was planning on adding a pair of perc clownfish or some blue/green chromies.
