lmao, i'm glad you're wicked happy!!!
As for the cleaner crew, CBS (coral banded shrimp) do not do well with other shrimp... they'll eat 'em. You can get 2 cleaner shrimp, and 2 peppermint shrimp, or 2 fireshrimp. (these guys are blood-red, and wicked sweet...lol)
You can get more hermit crabs, and you might want to get some snails too. Turbos are good, only if they fall off the glass and land upside down, they can't flip over, and they'll just lay there and starve to death... Nassarius snails are sandsifters, and are a great addition to any tank!
