which is better

Mike, you have lots of water and you'll be able to maintain water quality really well. But the additional 6 inches here and there isn't going to cut it for 4 tangs. I have 2 tangs in a 150g. That gives 10sq. ft. for 2 tangs. You only have 15 sq. ft., not double the 150g area. Maybe three tangs would do OK, I just think 4 is pushing it. Will they die and your tank burst into flames?? Probably not. They will probably not be best friends though. I think your tank would make 2 tangs really happy. In the end, it is your tank to do with as you wish.
