There are 250 types of Damselfish in the world, and I have run into six while snorkeling that I will share. This includes a fish that I visited over a five-year period, a Giant Damselfish. This fish species has a well defined small territory, allowing you to visit one over time, as I have done. In this video, Damselfish of La Ventana Bay there’s repeated photos of this fish, each dated. There is also a scene showing close-ups of nesting behavior, and how they change shades of blue for purposes I can only guess are for reproduction, but don’t know fully.
