I think just because something is "possible" doesn't necessarily make it "likely".
I try to keep an open mind on things because I've learned some surprising things over the years - in life in general - not necessarily only about reef keeping.
Having said that, I think just because something is "possible" doesn't necessarily make it "likely".
Do you guys remember the story about the guy in Australia that had his legs eaten into by some kind of amphipod? He was at the beach, in the water and noticed his legs bleeding below the knee. He got out and had to go to the hospital, where they discovered it was some small amphipods or crustaceans. So yeah weird stuff happens. I mean, it's not going to stop me from diving every weekend, though. Right?
