As dumb as a box of rocks!
I needed to find the right rocks for my planned scape. I knew the ones I wanted, but I can't tell you what they are called, as I am no geologist! They are dark grey with white lines running through them.
Anyway, where I am working there is a big lake, and a few years ago they built a dam wall to increase the size of the lake. This dam wall has been protected from erosion by the use of tons of the exact rock I wanted. I am not about to advocate the theft of rocks from dams, but there must be a million tons there(slight exaggeration!), so my removing 25 kg for my tank shouldn't effect the structural integrity of the dam!

Omnomnom! I'm glad to hear that they'll be fine, they're very beautiful.
