About two months ago I got a lawnmower blenny. As soon as he got accustomed to the tank he immedatley attatched himself to my pair of clowns. He swims with them all day, they sleep together at night rubbing up the each other. They have never been aggresive towards one another at all. They act like three friends just hangin out. But the wierdest part is that he loves eating their poop as soon as its in the water he chomps down on it. What gives? Is this normal for a blenny?
