Breeder box question

[Duff0712]

I was thinking of getting a couple finnex breeder boxes for growing moss and breeding projects with shrimp.

I was wondering if you all would recommend using 2 on a mr Aqua 12g long trimless or would it cause too much strain on the tank?

Or even just one?

I would not hang a breeder box on a rimless tank. That seems to be alot added unnecessary strain on the glass and seams.
