"Tuskfish readily accept meaty foods, fresh, frozen/defrosted and live. Crustaceans, shellfish, fish-flesh are all fair game. The best colored, least damaged specimens I've encountered have been kept off live foods; too often these result in the wrasse dashing itself into something hard and/or sharp. There is also considerable anecdotal evidence of increased agonistic or aggressive behavioral problems linked with live food offering.
Hunger strikes of a few days to a couple of weeks (for larger individuals) do not necessarily spell doom. Check your water quality, enact a water change, and proffer a shrimp-like tidbit on the end of a plastic dowel or tubing near the front of your tusk's cave near "night-time". Otherwise don't panic and do something more drastic if your other livestock is fine."
