Me? Solo? Into HIS tank?
Not a chance!
He's miffed enough that I opened the live rock before he got home.
Anyway, I'll be taking over the 40, when all the corals and fish are moved over. I'll be getting a frog fish for it, so there's no temptation for me to put anything 'extra' into his tank.

I know, we're weird--his tank, my tank, all the same, right? HA!
