I have one juvenile angel (nickel-sized body - maybe an inch, not
counting finnage), and he still bosses the tank. Although currently
"dwarfed" by the 2 dwarf gouramis, he acts totally unafraid and
investigates everything in the tank. He even nibbles my arm and
fingers when I am doing stuff in the tank. Trying to see if I'm
edible, I think. He's never acted afraid - always "Mr. Pushy." I can
see how even small angels could get to fighting sometimes - they can be
quite the characters. Good luck with your remaining two.
