My Fighters "play dead". They dive bomb intot he plants and stay motionless for ages. Then I tap the glass and they shimmy and shoot out! Then they expect food. :roll: I also like putting a mirror up to them and see them flare.
Oh, and my platy fry are quite possibly the stupidest fish ever. They don't see the food that's right in front of them until it hits them.
I think it's cool how my big BN acts all macho like the boss of the tank but as soon as I walk up to the tank, he's the only fish that hides. :lol:
