Whilst on Spetsis, (fantastic island,don't tell anyone).
Had trouble photographing the fishes with the use once underwater camera from Boots due to the bread floating, so...
saved the crust from the pizza, found a length of string and a rock, tie bread to one end and rock to other sink it all and there you are, bread at a depth so you can snap away, Hans and Lottie Hass eat your heart out.
Anyone know where on the webb I can find pictures of the small fish I'm likely to encounter in Greece, (don't mean sardines halfway down the menu on the left hand side)! Cheers, Tony O-P.
