Aggressive combinations in a tank

Ok, does anyone know what kind of tropical fish/inverts I could put in with a Leopard Shark Without something dying? Looking for a colorful feel to the tank I'm going to get.

theres alot you could do! but it really does depend on tank size.. though as a colorful invert a lobster would be fun!
