I think they're beautiful! Okay, so they're ugly, lol. Their saving grace is their personality: always curious, up at the front glass when you approach and very aware of people, the " hopping " way of movement that comes with lack of swim -bladder makes them interesting to watch, and they're more docile than most of the other Tangs I've kept.
I could take pictures of my pretty fish but that would be no fun. Everybody's seen Calvus, trets, sexis, and synos.
