Ok - yesterday I picked up 3 little angels from my trusty LFS. Two are about quarter size and one is a bit smaller. One of the larger ones is being a jerk to the other two. I know this is natural/expected, but at what point should I be concerned? Is there something I should be doing or watching out for? (I have never had angels before....) I don't want to wake up to dead fish if there is something I could have/should have done. Thanks!
