awesome

I think things are going well in my tank so far... I just added my first critters Tuesday, nitrates are at 10, nitrites 0, pH 8.0, water temp. is still fluctuating day to night about 78-81 (so much for the hopes put in my new heater) but all is looking well, and I think my hi-fin goby (who made a lovely backflip out of the tank) is hanging in there and he has a good appetite. They sent me a carnation coral in a nano coral pack that continues to just lay down on the rock, so I'm pretty concerned about it. Everybody else is looking good. How long should I wait before adding more frags? Do you know where to get
fire shrimp for a decent price? That's the one thing that didn't make it through shipping for me. I'd welcome any thoughts.
