As we passed a dune I saw a tree trunk of about 30 cm thick and about a meter long stuck in the bottom. We headed North&nbsp;as the visibility was good in the SW area. Also much more copepods in the SW area then in the dive area.The further we approached the restaurant the worse the visibility got.&nbsp; At 5 mtr an orange object caught my eye and it was a goldfish. It was damaged at the tail.
