It all depends...
Is your neon damsel the "all blue" one? Reason I ask is one of the books I have says "neon damsel" next to the all blue one and the one that looks like my avatar pic.
I put two of the Javanese damsels (in my avatar) into my 46g from the beginning and the bigger of the two would chase the little one around a bit. However, now it's only if they get really close and irritate each other. Not as much as is used to be.
However, a few months later I put in the A. Percula clown and have never had a problem. The Javanese is supposed to be one of the more territorial of the damsels (didn't know it at the time I purchased them), but I haven't had one bit of a problem with them and my clown. Actually, it's kind of funny because the clown will hang out with the big Javanese like it's his big brother or something and it doesn't bother the Javanese at all. Has never gone after him once, that I've seen.
So, maybe I got lucky and everyone is cool with each other and I'm the exception...don't know.
HTH...
