Healthy angelfish will always come to the surface of the water to feed. No matter how they have staked out their territories, they gather together whenever they see me approaching the tank.
This tank also contains some fruit tetra and electric green tetra. They are larger than neon and glowlight tetras so they can hold their own with the angels. They are also faster than the angelfish because the angels' long, flowing fins slow them down in the water, so they can quickly scoot out of their way.
The four angelfish in this tank are each around eight inches tall and growing.
