I got my first fish for my saltwater tank yesterday. He hid out all day, as expected, but he came out for a bit last night. He's super tiny--much smaller than I expected. You can get an idea of how tiny he is by the two snails in the picture. The black one on the glass on the left is a dwarf cerith, and the one above is a nerite.

He was paired with a red striped pistol shrimp, but I haven't seen the shrimp since I put it in the tank. :( Hopefully it will come out soon, and they will find each other again.
