Hi, so crazy question but I have a Betta tank (unoccupied due to age rip) and a ball python tank, thinking of building something to combine the two (fish tank on bottom, snake on top) so my snake can swim more, (loves the pond in the backyard, not a humidity issue just is weird and likes swimming) and I have more space. Not getting another fish and they are ruffly the same width. Thoughts on how this can go horribly wrong?
