My six-line and clownfish are actually quite comical to watch. The six-line is kind of like the annoying little brother. He likes to hang around the clown, but also likes to antagonize her from time to time. For the most part, the clown just ignores him when he decides to nip at her, but if he really starts annoying her, she'll take a chomp at him, and he just swims off and tries again later. All in all, though, they get along very well. The six-line is the only creature in my tank the clown tolerates close to her anemone.
