Cories are crazy like that and sometimes have the tendency to headbutt things. Have you noticed them swimming to the surface to breath air?
I don't think you're overstocked at all.
What type of filtration system are you using? I know 40G don't come with starter kits.
hopefully this link works. BTW, despite having that betta hammock, Baloo normally sleeps on the gravel towards the back left side. This morning, I found him sleeping on top of that blue plastic plant. It was pretty cool to see him wedge himself in there.
