I am a real lover of bright colours, so you can imagine the sorts of fishes I'm instantly drawn to! 
I look at photos of some and think 'how boring!'
But, lots of people keep these fish so there must be something about them.
One example is panda cories-I saw a pic, thought, not much to look at. Then I saw a shoal of about 15 in a huge display tank at a LFS and they were great. En masse, they looked like a dolphin swimming about!
So, 'sell' me your boring-looking-but-interesting-in-other-ways fish
