Cleaner wrasse in a deep sand bed

I know they do not prevent but they do eat and help fight off! Also very nice looking!

Actually, they do not. Cryptocaryon irritans (ich) is below the skin and not available to cleaner wrasses or cleaner shrimp. Survival rate of cleaner wrasses in aquaria is dismal.

Actually, they do eat ich. In a 2002 scholarly paper by A.S. Grutter on the relationship between cleaners and parasites Labroides dimidiatus was found to eat the trophonts of Cryptocaryon irritans from specimens of captive fish, so they are "available" somehow.

For the sake of clarity although not to belabor the point:

From "œA.S. Grutter on the relationship between cleaners and cryptocaryon irritans":

"œAlthough the cleaner fish, L. dimidiatus ingests the trophont stage of the parasitic ciliate Cryptocaryon irritans, the agent of white spot disease, the cleaner did not significantly affect the parasites abundance (Halliday). This is due to the inaccessibility, the smaller size, and the rapid population growth of C. irritans as well as the uncooperative nature of the client."

If you are interested. Google Scholar will give the entire document.
 
Get a cleaner goby instead. Looks very similar, just smaller, but will actually survive in your tank.
 
I have a pair of cleaner wrasses, they do quite well but do scavenge for pods and stuff. They don't dig or sleep in the sand, so your sand is probably safe.
