Aquarium is on the northern side of Grgur. We normally anchor the boat where you can see a tiny beach coming down from Grgur.
This dive site is a wall. We start keeping the wall at our left shoulder. The cliff goes down till 40m deep. It is covered with yellow and orange sponges, big and tiny holes where conger, octopus and lobster are hiding. The wall is covered with different species of nudibranch,such as the giant doris, dotted sea slug, pink flabellina, yellow tylodina (difficult to spot because is hiding on yellow sponges) and for the lucky one Antiopella. On the way back, with the wall on the right side, look up and you can see schools of damselfish and different type of breams. The safety stop can be done in the shallow area close to the anchor. In this area you can look for anemones and try to spot the harlequin shrimp or the spider crab hiding in it. Aquarium can be a shallow or a deep dive, just stay at the wall and keep your depth.
