So I went to Sri Lanka in April, stayed in Unawatuna, near Galle. There is a quite a lot you can do there, there is a series of videos by some east europeans on youtube. I had a flu and couldnt go more than a few meters deep this time, so just did some snorkelling. Here is the video. If you swim to the edge of the bay there is a reef all the way around the headland to jungle/ rumasalla beach on the south side of galle bay. You can also get boats out to reefs and see larger fish like that. Its a bid hard to see on the GoPro, there were quite a few spearable fish in the bay, many more on the reef by the headland though, but I didnt go out there this time.
