Looking to start breeding! What do i need to get started?

It will be much taller than a 3-4 slot, but it takes up the same floor space. The pvc racks aren't hard to move, I would suggest though if you get a 7+ stack to add castors to the bottom so it's a bit easier to move around. They are WAY lighter than any wooden racks for sure!

is that too many though? i don't wanna be stuck with too many tubs, or too little! haha. how many would you get in my situation?
