I was hoping to have a hippo tang, however after reading the sticky on tank sizes for tangs, my 100g isn't big enough for it sadly![]()
That's really bad advice. Hippo tangs get really big, are prone to ich, and do not belong in a 4-foot tank, ever. A powder blue in a tank that size is also a bad idea.I have 3 tangs (Hippo, Yellow, Powder Blue) in my 115g that get along great. I'd suggest any one of those as long as you have a 48" or longer tank. Flame Angels are also very cool. Lots of options in a 100g. I'd get some sort of shoaling fish as well.

To the OP, you'll be much happier in the long term keeping medium to smaller fish, with just one or two "showpieces." Gobies are great fun, as suggested. You could keep a pistol shrimp with it, but I would worry about your hawkfish.
You could do some wrasses, if your tank is well covered (like with 1/4" bird netting). Chalk bass, a dwarf angel, a lot of possibilities that are easy to keep, active, and attractive. I would look around at Live Aquaria and other websites to see what strikes your fancy, then ask about specific fish you're interested in.
so far what I have is a yellow tang, coral beauty angelfish (both which I just got yesterday!), 2 occellaris clowns, 1 flame hawkfish, and a dogface puffer.
My 100 gallon tank is exactly 60" long and I'd say about 2' or 2.5' feet deep.
