hillstream loach?
u can see their hearts!
But they are not tropical, or plecs!!
Hillstreams are coldwater fish, they can be kept in cooler tropical but they won't be as active etc.
How about a clown plec? Hmmm the plecs I have are pretty funky. The L134 is gorgeous looking (yellow and dark brown) and is quite skitty and the L052 is beige and brown but he changes colour and contrast dramatically to blend in with things.
A King Tiger (L066) or Queen Arabesque (L260) are cool too. Then obviously there's the zebras (L046) (eh, Alien_Spawn!) but it depends on how much you want to spend.
Try looking at Planet Catfish's cat-eLog and go through the plecs and se what you fancy. It's how I decided on mine.
