Hi. We are in a rental property. My husband's colleague gave him a fish tank two weeks ago with some small fish in it. We have a real estate inspection tomorrow. I didn't even consider telling them as I figured a pet refers to an animal that is let loose like a dog or cat. I class fish as ornaments! Hubby pointed out that this might be going against the terms of our lease. At this place small pets are considered upon application but we didn't have a pet when we moved in. I'm thinking I should just not saying anything and see if they do.......any suggestions?
