I think. After that, CG is what we have to worry about.
Thirty pounds of tetras 12 or 16 feet from the ground (if I read your post correctly), held by an arm that has to weigh 20-40 pounds? Yeah, I'd do the CG calculations if I were you.

But if it falls over really dramatically, can you please post video?

Seriously, I expect to see a lot of robots s-l-o-w-l-y rotating to the ground, losing the CG war. I kind of expect to see some teams driving out from under their top-heavy bots. Let's see, applying a force at ground level underneath a structure 8 or 10 or 12 feet high, with a high polar moment of inertia...
