Barking Sebae Clown?

[nicenakago]

Anyone ever heard a Sebae Clown bark? I introduced a Sebae clown to my 26g that housed a blue damsel and VERY aggressive 3 striped damsel. The 3 striped was the bully before the clown was intruduced... but when the clown faced off with the 3 striped damsel, they both sounded like they were "barking". My wife is convinced it was the clown... I thought it was the damsel. The sound only came from one of them. Of that I am certain. Any thoughts?

my roomate's three stripes do that. those are some very aggressive fish imo. he has three of them, and they've done it to each other before, so my guess is the three stripe is doing it.
