It's cool that you seek advice, but either way you won't go wrong. One thing to consider is that if ever want to get a 2nd they might not get along, so if you have an inkling that you'd like 2, it'd be best together. I've had one and I currently have 2 and the interaction between the male and female is entertaining, especially with a 'nem in the picture. The 2 clowns are always together and near the 'nem for sure and don't bother any other fish, except with all the room in the tank I have, there a coral beauty that hangs around them that they don't particularly like. Even though they try to protect their area, the coral beauty has to spend most of it's time tormenting them, and they in turn chase the coral beauty out of their area (or try to) No contact, just kind of a you hit me first, no you hit me first standoff. The other fish can swim right past them and they leave them alone, but the coral beauty is a different story and knows it. Every so often the female clown with toss the male out of the 'nem and the male gets pis sed and will try to bite the tail of the female. They are cool to watch, but they are definitely not afraid to attach a hand, so even with one you have to keep an eye on it/them when and if you have to stick your hand in your tank. Doesn't really hurt but when you see a clown come swimming and bite your hand you jump and they do seem to know how to find a soft spot between fingers, etc.
