Sika Tanki is situated also on Grgur Island, after Canyon. This dive site is famous for the current and for its colourful wall. We anchor at 8-10 m deep, and we start the dive following the anchor line. The dive site looks like a figure of 8. We usually start from the middle and keep the wall on our left side. The external wall goes down to 40m and is cover with colourful sponges and gorgonians. Following the wall with your left shoulder, you will end up again in the middle, where there is a small tunnel at the depth of 10-15m. If you follow the line of the 8, now you will be on the wall with your right shoulder, ending up going between the dive site and Grgur island. This part is the shallow part of the dive, where you can look for nudibranches, scorpion fish, octopus and if you look in the anemones you could find spider crab or more likely harlequin shrimp.
