can you drill a Hagen tank?
 

Are these tanks able to be drilled or are the tempered glass?

I think the bottom pain is tempered. Not sure about the sides.

I asked ol' Rolf himself. This is the reply is got:

Dear Franklin Shiu,

We thank you for taking the time to contact us.

On all of our aquariums we use non-tempered glass. We hope this helps.
