I have approx. 3 of these guys that hitchiked on rock from OA...they were in my 72G for 5 mos. and now in my 150 for 1 month...never seen them go after anything but algae and purple coralline. I havent noticed anything else disapearing. I did notice that they have the same claw tips as my Emerald...for scraping.
