Thanks for the kind words!
The starfish has not been seen in a long time. I hesitate to say it is gone as saying that usually means I see the critter next time I look at the tank.
On the Goby/Shrimp pair they did pair up immediately, or at least overnight. At the LFS the Goby was kept in an Aquapod 12 with a different shrimp. They couldn't catch the shrimp so they grabbed one from a different tank. I was worried the Goby would not like the "strange" shrimp but I don't think it mattered at all.
I don't run a skimmer but I did swap the stock pump for a maxijet 1200. In the back chambers I have live rock in chamber 1. I also use some mechanical/chemical filtration in chamber 1. The water spilling over the return falls onto this filtration sandwich: Top is floss, then bag O carbon, then air conditioner filter, then 1/4 of the supplied blue block to hold it all up. I change the carbon once a month, floss once a week, air conditioner filter once a week or every other week, and I swap out the blue block weekly.
I change 3.5 gallons of water weekly and use Instant Ocean. I don't dose as my alk/Ca levels are staying static with just the water changes.
And because I got too talky, here is a pic:
