Fly Trap Closing by Itself
About a week and a half ago, I received a Venus Fly Trap through the mail. It was pretty healthy, and has been growing very fast :) But I now see that one of the smaller traps near the bottom of the plant seems to be slowly closing over the course of a few days. The trap itself appears healthy, and has no rot or other decay.
Is this behavior normal, or should I be worried? Thank you for your time.
