A bit of an odd request, but would it be OK for me to install a small tropical fish tank in <my dept>?
I am a tropical fish keeper and I find them very calming. Research has shown that having an aquarium in your office helps to reduce blood pressure. Other studies have shown that fish at work can help to reduce stress.
I would be happy to set it up, stock it and maintain it at no cost to the company other than a small amount of electricity. I have spoken with <colleagues> and they have no objections and would be happy to feed if I was out of the office.
