This past weekend, the reef store recommended we purchased a lawnmower Benny to help us with the GHA issue we are having. The first night we added him to the tank, our watchman goby came out a little. Ever since I haven’t seen him (so a couple days) I’ve seen the tentacle of his pal, pistol toward the front of their tunnel, but no watchman... is it typical for them to go into hiding when you introduce a new fish? Just hoping he didn’t get into a fight with the lawnmower Benny the first night .
