Why can't we have some ducks ?

Reading Mr Sriraj's post I gather that the fountain would soon be functioning at Mantri's. I wish we could have ducks in the water, as they have in this pond at the Blackhawk Mall in Danville CA. It is a major attraction for children visiting the mall. If our fountain isn't big enough for ducks, we could at least have some colourful fish. I am sure children woud love it.
