I am starting to see these guys more and more in my tank. Now mostly on pumps, on the back wall and on the bare bottom glass. So far i "think" they have not reached the rock work yet.
Read a range of opinions from them not harming much to being bad for the reef?
Any thoughts? Any natural predator to rip them apart?
thanks
