I've had Edward for a few weeks now and have been reading up on Betta care. One article I read said that some Bettas like to push around ping pong balls at the top of their tanks. Not having any ping pong balls available I took a rubber duck that I had sitting near the tank and placed it in. Edward took one look at the duck and started freaking out and hid under a rock.
I removed the duck and coaxed him back out. I showed him the duck on the other side of the tank and he didn't react but when I tried to put it in again he freaked out and hid again. Is this normal?
