Lol. We are all sick I think.
No Blenny is good for a new tank. Lawnmowers are great, but I'd wait 6-12 months before you get one. They need aged liverock and lots of film algae to eat. If you ever watch one in someone else's tank, or the store, they are always, always, always grazing. I have one...and it never stops! It's hard to find one that will accept any food at all. Mine hasn't liked a single thing I've tried to give it, which has be concerned.
'Bout the snails, my suggestion is some nassarius or llynasa snails. They rock, and sift your sand at the same time.
Check out ebay for great deals. I got mine from a seller named cm-marine. I ordered 50, and I got 101! I gave most all of them away to people.
I think a goby would be fine, but would cut it off at that.
Also, I'd add more peppermint shrimp as well. I just like them for some reason though, so that's just my personal opinion.
Nice tank! Now I gotta go hit up the LFS tommorow and see what I can find!
