The new tank is looking great, nice anemone :) That would be awesome if someone still had your stuff! I've always wanted to check in on some of fish or old setups I've given away to see how they've done. Hopefully someone responds
I'd be a little hesitant even though its on the exterior wall and on perpendicular joists. A 120 is 1000+ lbs and being on a second floor is always a little bit more precarious. I would call somebody to check it for the peace of mind
Add clown triggers to that list. I'm hoping that wrasse and anthias are next. They have had success with Borbonious anthias, so I'm sure that they can apply that to Lyretail, Bartletts, etc.
I don't have a thread for my 29 gallon, but I am in the process of starting a 75-gallon build, so I think I may create a build thread on Reef2Reef or here!
Nassarius snails look cool and are great for the sand. However, my favorite is trochus. I also have hermit crabs, but they always seem more interested in attacking each other than scavenging.
