Post a pic, always love to see other guys tanks. Nanos are probaby the toughest marine tank you can ever setup, once you master a nano tank you can do just about anything. Blood/fire shrimp are my favorites!! the nano above has no fish, just a coral banded shrimp.What corals do you have in the tank?
I love my blood shrimp, but he hides a lot unless it's feeding time. My other favorite guy is my Fighting Conch. Nanos are a bit of work - but I enjoy it. I'm keeping up with my weekly water changes just to be sure all my nitrates are at zero.
After seeing your tank I've decided two things:
1) I went out and got myself some frags since I previously only had a few green mushrooms. I got myself a neon green candy cane, 3 button polyps (one of them a cool ice and fire one with a bright orange skirt), green star polyps, and an open brain coral.
2) I also decided I'm going to do a DIY LED retrofit using Cree LEDs. This will probably happen in a few months since I want to make sure I have my research completely done. Then, I will probably try a some SPS and maybe a clam in the tank.
