update***
It seems the Leaf has opened up the predatory characteristics of my Angel. She (I'm assuming I'm knowledgable enough to sex her) won't attack the Leaf but will compete with it for feeder guppies. Before the leaf, I was able to add in small Neons or Cardinals and while she would show interest she would never go full on attack mode. Once they darted, she would lost interest because she knew flakes/pellets or something frozen was coming.
NOW, she is a different animal and go full stalk mode. Yesterday she tried to get a guppy who was swimming in the open at the top of tank. Guppy would see her coming and then dart away. Angel did something new and dropped down 12 inches or so into cover and then came at the guppy from underneath.
Works out for the Leaf though as when they dart away from the Angel, the Leaf is 'floating' nearby with the hoover vac waiting...
Very cool fish.
