as you wade out from the rocky shoreline,there is a dropoff right in front & the purple tangs are swimming all round you.local kids are playing in the water & splashing & making a noise as kids do,the tangs are swimming right amongst them picking away at the coral rubble for food.at one stage there must have been about 30 mixed species of bristle tooth & purples all at the shoreline ,but camera was out of water already & i was to cold to go back in .interesting is that the water temp was 22 degrees that day & very choppy due to wind factor.
