This video from YouTube shows the harbour in Puerto del Carmen. To the left, the boats that take tourists and divers out in the daytime moor for the night. On the right-hand side are the restaurants with there tables overlooking the water.

At about this point there are lots of little fish in the water, waiting for visitors to through them scraps of bread to eat. They often fight over the bread and can cause quite a splash. Every now and again a stingray comes into the harbour to feast on the fish.
