I've had 2 males and 1 female BN in the same tank for 3 years. Never had any babies for some reason. Yesterday I noticed the female looked a little beat up so I dropped her in the tank with my one angel. Good heavens. For 3 hours the angel twitched, jerked, charged, tried to sneak up on that BN until she looked like a psychopath.

This morning the tank lights come on and away she goes again. She is used to little fish surrounding her and does not know what to think of this BN. Fish are so weird.
