Generally in a 100 gallon tank, which this is, damsels won't bother non-damsels (except chromis)---but I've never had one this large (4.5") and I am having to choose between pep shrimp (spendy, in enough numbers to hit on one that will eat aiptasia) or a matted filefish, which the damsels may even pal around with, who may or may not eat them. I'd kind of prefer the shrimp, because they won't generally eat (may pester but won't harm) corals, while filefish may at least ding softies (mine are stony, but I have no data on their habits with stony coral.)
In other words, between the shrimp and the filefish---anybody have experience with survival of shrimp with big damsels, or with filefish habits with stony coral?
