If the angelfish are about to lay eggs do they get more aggressive/hungry? I saw one of my angels with an otto in it's mouth, but the otto got away thankfully. One angel will eat so much it's belly looks like it's going to pop! If they pair up can the male tell that the female is pregnant with eggs? What other kind of behavior should I expect? I had some angels before that would have eggs but that was years ago and I don't remember any special behavior on there part.
