They are not designed to clamp to an existing hood/canopy but to rest on the glass rim itself.

I think (im never sure lol) that we have already established that the arcadia hood was not meant to fit on the rim we have already moved into a more McGuiver approach.
Alright.
So here's what we have here.
Picture one is a standard rimmed tank, and what i am sure rests under the prefab top/rim.
Picture two is of the fabricated edge to the best of my horrific MSpaint skills.
The single red strip is where you would cut or melt a slit the length and width of the leg of your arcadia stand legs. Mind you, all of this is to just show for the one foot you showed us.
IF for some reason there is only 2 legs and it relies on that screw connection to steady itself:
A: That kind of light scares me on a tank, too many ways for it to fall
B: This design wont work for you. And i have failed.
Now, assuming there are more legs. and you aren't afraid of a stove and a butter knife, or even better, a dremel with a cutting disk. Lets look at 3 and 4
3 is simple enough. Just a close up of a marked up area and a shakey hand cut (cause i have hands like a sugared up 6 year old... on meth).
Well talk about picture 4 after you look at it.
lolpinkright?
No serious. I drew it in pink / horripurple in wireframeish view so you could see how the foot will rest on top of that flat spot, and sit in the groove you have cut / melted into the angled piece. easy enough to do, and not even required to be accurate to the edge,(mind you they still have to be in line with one another to work) but the further from the center of the top edge, the tighter the fitting will get.
Believe me, i tried to draw a few examples of what i mean there but i am not that good with freehand isometrics. just nope.
But either way, if i missed something or need to better explain something more, let me know.
