okay RT6, lets take these Q's one at a time shall we.
CUC - If you put one in now, what would they "clean up?" Now, this is not to say that you can't add a snail from your old tank, I think that would be fine, but you don't need a whole "crew" at this point, do you? Are you going to buy a new CUC from a vendor, or pick and choose your own from the LFS? Beware of some of the crabs that they offer, not all are as good as they claim. Look for a variety of snails as well, both sand dwellers and glass / rock cleaners.
Six line Wrasse - I have not kept one personally, although I have been tempted several times to try and keep some snail / worms under control. I have a small tank and do not want the current peaceful balance upset by the 6LW, as I have learned that sometimes they can be a PITA to other fish. Not worth the hassle to me. You may be fine in your 90. I think this is another issue you should consider at this point. You have been mentioning a lot of different fish that you want to keep in this tank. There should be a definite order in which you introduce each specimen into the tank so as to minimize the stress amongst them. Once you settle on a list of the fish you would like to keep, start another thread about the right way to introduce each fish to the tank. It should make for a good thread.
As for other types of wrasses that may work in your tank, post a thread in the fishes forum and seek advice from some of the folk there. There used to be a whole sticky thread on the wrasse family with more info than I could digest. Personally, I think the flasher wrasses are way cool to watch in action.
