it would be a fish but if you cant spare them atleast 10 mins to talk to them then they are not for you. Research shows that fishes who are given attention live longer compared to those not and they even repond to you!!!!!!! Quite frankly living in bombay or elsewhere makes no difference. If you love your pet enough no matter how busy your life is you will find time for it. Its what we would do for our kids and family
