As far as I can tell the jury is still out on that one.... Mine won't even stand up to blue foot hermits that are only a half inch and he's an inch and a half (without legs). All he ever wants to eat is hair algae and cyano
off my rocks and scavenges for decay in my sand bed. Imho
I think of you have a messy eating stock that they probably won't even look at your live stock, just their waste, but all I have with mine is live rock, coralline algae and the usual hitchhiking critters and 3 blue foot hermits. Reading reviews on them it doesn't seem as though people are having problems with them....
