I was just reading through a few of the posts and on one (regarding fish tanks I think) Oregonwoodsmoke stated something to the effect of "So far, the tenant grapevine hasn't put out the word that tenants can have emotional support fish."
I just kind of chuckled to myself thinking "ok, you can have the fish as an ESA but not the tank".
One of my kids had a fish at her apartment/condo - one day I was visiting and when I went to wash my hands in the bathroom sink it was very slow draining. I asked her how long it's been like that - she said "oh, I don't know - a few months".
I took the trap apart and although she didn't have the fish any longer - I found a bunch of the blue stones. I just showed it to her and said "about the time you started cleaning your fish tank in the sink? - I'm just glad you didn't do it in the kitchen sink since it has a garbage disposal".
