There's an interesting story to this one. This is a smaller clown that I got later after the first clown who has a black spot on its body. The interesting part of it is, they were together for awhile, beat the crap out of each other, now spot (the other clown) lives in my friend's 120 gal. Now that this smaller clown is alone, he develops a black spot just like the other one, next to the white bar on top.
