How do I moniter a new fish if I never see it?

Locally, pricey, at an LFS I believe you are not fond of. I'll be keeping a close eye on them as far as that is possible. The adult male is out cruising all day and the juvi stays put in the rock pile on the right side of my tank. So far no conflict, thankfully. The juvi initially got more flack from my Blue Devil Damsel, but that has since eased to a non issue as well.
