"But my main question is do I really need to secure the cylinder down? And if so how should I? "
I would say the answer is no, especially if your co2 canister is inside that congested stand.
If there is an 8.0 earthquake, and your canister falls over, it won't fall over far enough for the regulator to be damaged.
If you experience that type of severe event, trust me, your new regulator will be the least of your worries compared the rest of your home and all the damaged valuables.
You have no reason, and no known precedent, to think you need to strap the co2 canister to the inside of your aquarium stand.
If you are worried about the canister falling over, I think the bigger concern is to have your aquarium stand bracketed to wall studs (not flexible straps/cables).
My kids like to be near our largest aquarium, to lay on the floor supported by their elbows to read or use a chromebook. I've trained them to respect a safety zone, far enough that the aquarium can never tip over and crush them in an earthquake. We are within an hour's drive of the San Andreas Fault (my favorite winter hiking area).
