Thanks for the comments everybody. I finally have a tank I really like. It took a little trial and error and looking around to find exactly what I want.
Right now i have just the yellow tang, 1 b+w striped damsel and 2 yellow tails. A few crabs and snails, and a blood/fire shrimp.
I wasn't happy with what I had and decided to wait until I got this live rock and new sand. Now I just have to wait for the chem levels to get back to perfect (0-0-0), before i added more fish.
LOL The hermit crab is only 1.5-2 inches with his shell. Its just he was right in front of my camera when I took the picture, so he looks massive.
And with 75g, its not really all that big. I read that 75g is a good size to start for a SW tank. If you want a lot of fish you'll want something much larger. I think I'll upgrade my tank if I move in a year or 2. I can then get a 180g or something even larger, and use the 75g as my sump.
