Answer the question about text:

We snorkelled first at Pulau Mamutik , and the boatmen were kind enough to bring us out to where the best corals were . There were red , purple , blue , green , yellow ... .absolutely amazing ! My guide even taught me how to skin dive to the seabed and see the corals close up , as well as any unique things like Nemo hiding among the corals . Another interesting thing was that he brought bread with him , and when it was scattered we suddenly became immensely popular with all the fish there .

Why are so many fish swimming around the narrator ?
The narrator is spreading bread .
