I'm so glad to see your tank. I am a newbie to saltwater as well and have the exact same little ten gallon tank with random equipment just like you. I have spent quite a bit of money though, on all sorts of stuff, but I think I have it about where I want it for now and I can just let it grow. Maybe if I can figure out how to post pics I will post one here. I'm so excited there's someone else like me!
I have a goby and pistol shrimp and you can see the pistol shrimp is a bit of a hoarder when it comes to shells. For a little tank like mine, they are pretty entertaining.
