Nice tank payne
very white sand........
I believe they should be ok on the 125gl, no problem as long you have your water in good condition and your levels..........
Everyone says that Tangs are too small for 55gl, 125gl, well sometimes they may outlive the ones that are on 5000gl with np. I agree with the rule that Tangs should be on a tank bigger than 125gl to have lots of space to swim, but in my mind 90% of the people won't and if they keep on check with their tank they will have a health tank....
If the rules apply to all, I believe all LFS would have 1000gl+ to hold all or many of their show fishes....
Nice tanbk and keep it up, wish my sand was white like that
