What with the coral cut now and all, the Slytherin moved over to one of the smaller tanks, which...was at the back of the class. Of course. If ANYTHING got on her bag, she was going to...well, she'd hold off on doing anything to anyone until the professor was out of sight.

Taking one of the smaller tanks, she started filling the bottom with clay, all the while keeping a close eye on the stubby purple coral she had cut previously. Hmmm. Did it hurt plants if they were cut from something? Did they silently scream? Did they have any feeling at all?!

And was she done filling this tank? That looked to be thirty centimeters. It was taller than the coral itself, but not by a whole lot.
