Murcos, I would skip on the lawnmower blenny, they really need a 55 gal
or larger to support their eating habbits. Maybe swap for a purple firefish or a goby/pistol shrimp combo.
The linka I would skip as well. There are lot of other stars that are more suitable for tank life. (small red star, serpent star)
The six line wrasse is a great idea, I love mine. The perc is a good idea as well, you might consider getting him/her a friend.
The snails/hermits/corals/snails/emerald crab also sounds like a good idea.
You might want to consider a cleanershrimp and 1-2 peppermint shrimp.
It also might be a good idea to skip the lettuce nudis and go with a tuxedo urchin instead. The ludis really belong in the ocean and don't really thrive in aquariums.
My tank is similar in size to yours, check out my sig for other ideas! HTH
