I came downstairs late and he was on top of my powerhead. I thought he was a goner. I turned the powerhead off and went to bed. This morning I came down and he is in the corner. I know he will move around some more until he finds a place to call home. I dont want him in the corner though, for one there is pretty signifigant bristle worm that hangs out where he is. I read somewhere that bristle worms may nibble on them. I will say he went to the croner that my clowns like to sleep in and they were investigating him. I have also read that you can put rocks or something to deter them from being where you dont want them to be....is this true?
