The file 'Fish Hospital 10mm Aquarium 3D Printer Model' is (stl) file type, size is 151.1KB.
I remixed this project: https://www.thingiverse.com/thing:3364837
I added holes in the back to reduce the weight.
I increased the glass support to 10mm.
I printed it with PETG.

You need support in the area that attaches to the glass, I added manual support in that area.
