I have a 150gal. tank with about 10gal. of sand. No kidding 5"to 6" sandbed. It's been up and running great for about 2 months now. I have alot of my large main rocks supported on crates. I have, snails, hermit crabs, sandsifting starfish, peppermint shimp, emerald crabs, a few corals, 2 perculas, and 5 chromis. I have been told this is a good time to add my blue spotted jawfish. I would like to have 2.

In a tank this size is that OK, and should they be put in at the same time? Do I need anything else in my tank? I would like any words of wisdom. I'm suppose to get them tomarrow, but I can wait if I need to.
