i rent right now and own a 75 right next to my comp. dont have plans on moving for a few years so im settled and im able to have a 20 gallon up soon YAY lol
My father in-law and I have become very good at moving 6' tanks, if need be just rent a fridge cart (bonus fridge carts don't drink beer!!) lol Good luck
Not trying to start an argument but here in Ontario if your renting already you cant be stopped from having pets. If you havent signed yet you can say you dont want the person to have a pet. after signing though even if it says no pets its void. its a weird grey area,
this is from personal experience
I rent and will be getting a 125 gal tank this summer. I have a 55 gal 20 gal and 36 gal. Our landlord is great we have 3 dogs a baby and no deposite. It's crazy but where we live it's hard to rent a place out for longer then a season. We take good care of the house and they know it. I'm getting an acrylic tank because they are much lighter don't crack easy so moving one is less stress then a glass tank.
I'm not worried too muh about it. The next house we move to will be our own. It all depends on the landlord and house.
