Marine nano-tank update

It's over a year and a half since we set up the little reef tank in my office and - fingers crossed - it continues to delight and entertain us. We've lost a few corals and two little fish, but sadly this is inevitable with marine reef keeping. Only experience will reveal what species are suitable for a particular set-up. We've given up on hard corals (although a little cluster of Duncans continues to thrive) Not only are they very susceptible to changes in water parameters, but our ancient Cleaner Shrimp is inclined to peck at them! Soft corals and zoans, on the other hand, grow and reproduce, filling every available rock surface!
