Which fish feel the most gothic, punk, or steam to you? Why? Links to pictures and/or detailed descriptions of the fish you like are more than welcome. Or feel free to post pics here, too.

I would think glass catfish (Kryptopterus) would be very gothy - they're like swimming skeletons. (Kryptopterus - Wikipedia, the free encyclopedia) They like to school, so you should get more than 3.

Black Veil-Tail Angelfish look like lace. (The Angelfish Society - Phenotype Library - Dark - Black)

That's all that comes to my mind right away, for really cool looking, peaceful, gothy fish.
