Does this lady have the permission to have an aquarium in writing from the first manager, also I would be calling the owner's of the building and see what they have to say. When I was about to move into the mobile park I live in I inquired to park manager at the time and he said I could not have our small dog. I made the application anyway and sent it to the park owners, guess what it was all approved. Turns out that manager had his own agenda. He's long gone along with his agenda. It may be worth her time to check.
Her new manager may not be able to force the issue if she was allowed in the past.
