Good Old-Fashioned Fish
(yes, Lembeh has some of these)
I can't help liking trumpetfish because they're so unassuming and have this laid-back look in their eyes... don't ask me why, but their manner reminds me of an old affectionate dog who's too old to nudge you or slather you with kisses or roll over for a belly rub, but wants to hang around with you nevertheless.
One thing I really like about razorfish is their synchronised swimming - I could watch them all day.
