Monty... or Don

I spied one of my goldfish swimming about in the pond this morning and rushed out with my camera. It might have been Monty or there again it might have been Don - I can only tell which is which when they are both out and about (Monty is the larger). Now goldfish may very well only have small brains but they are highly adept at sensing danger. As soon as Monty (or Don) was aware of my presence he slipped into the piece of terracotta piping which lies at the bottom of the pond and stayed there; presumably to  join his friend (Don or Monty as the case may be).
