I think everyone's covered most things tbh ..
As mentioned already those log hides aren't really fit for purpose as they are just not gonna feel secure in a hide with openings at each end .. imagine if it was you camping in a tent with two openings
If it's big enough and you're set on keeping it , I'd put it in a corner and use the glass as a block for one of the holes ... it will also look better anyways as you're not supposed to put /place ANYTHING exactly in the middle of a tank / Viv / photos / painting .. ..
