I just bought myself a pair of -Corydoras sterbai- that are just beautiful! They're a tan background covered with tiny little beige spots. The neatest thing about them is that their pectoral and pelvic fins are bright, bright, bright orange! They can cost up to $10 a fish, but I think they're so pretty they'd be worth it.
I also just got a -Horabagrus braychysoma-, or sun catfish. It kinda looks like a golden tan channel cat, with a black spot just behind the gill operculum that has a bright golden halo around it. I didn't realize it, but this poor guy is a shoaling catfish, and now it just paces the glass back and forth. Hopefully my manager will order more for me, I would like to get him a pair of buddies. It also likes to chill out in the cave when something spooks it. It cost about $4 and change, but another beautiful fish.
Go to the Planet Catfish website. They have a picture of every possible catfish in the world, I'm sure you can find something that appeals to you. I made myself a shopping list!
