Landlord wants my tank out!

[Jakegr]

I have found if you ask up front "can I have an aquarium" before you move into a new place/sign a lease, the landlord will be fine with it. One time I had to put down an extra security deposit, which is legal for the landlord to ask if you have a pet. Most leases do specifically mention no waterbeds/aquariums unless permission is given, although I know that wasn't the case with your lease.

Good luck finding a new place though! I don't think you will have trouble finding one that will allow an aquarium. He sounds like a bad landlord, so it is probably best to get out of there anyway. Moving an aquarium is a huge PITA unfortunately.
