I recently bought a pair of clowns and had a choice between about four types, all priced the same. I narrowed it down to a pair of B & W saddlebacks or regular orange ocellaris. I thought about the saddlebacks a lot, but ended up getting the orange ones for two reasons: they add an incredible splash of colour, and they were tank bred.
I like the idea of getting one black and white and one orange and white, that would be a great looking pair.
