Ok so I had a 40g breeder made for me and the hole For the overflow was drilled in the wrong location. I re-drilled for the overflow, but now I’m not doing saltwater.

I want to put my axolotls in this tank but can’t obviously with the 3 holes on the back. would I be better off plugging them with spigot’s or siliconing 1/4” glass squares over the holes.

in the end I will be putting a 3D background from Universal Rocks so none of the repairs will be seen.

the thickness of glass is 3/8”
 
I would glass over them.
