great pics I REALLY like how you have macros growing in your display. It makes the tank look "real" as opposed to a bunch of rocks with specimans setting on it.
I love the green macro in reef tanks... its such a wonderful contrast to the pinks and blues of the corals. All the copepods and such love it too since it provides such great shelter for them.
I did have a tank in the nano contest... a 5 gallon tank. After the contest was over I combined it with another 20 gallon I had setup to make my 33 gallon reef tank.
I'll have more pictures soon, maybe some of my seahorse fry if I can get any to survive this time
