you gotta walk the water twice a day for 2 hours each trip to keep it fresh and in shape, then you need to feed it regularly (you'll know when he/she is hungry), mostly beef and salt cubes, maybe a bowl of bovril
then you need to groom it, for that use half a bottle of soap and a trusty dog hair brush, and please give your water lots of attention
and give him/her a cage and pillow to sleep on
