looks very nice. you were talking about burrowing fihs earlier, if you decide to get one, may i suggest the engineer goby? very neet hardy fish that looks like an eel! i have one in my 55. as juviniles they have horizontal stripes, and when they get older, the stripes turn to be verticle. they get to be about 1' long. i have had mine for about a year, i got it when it was about 2-3" long and now its about 7" long.
it loves to hide in the rockwork in its little sand cave. will eat right out of my hand and will let me pick it up too! they have a great personality.
