Other Observations: One module landed on its side during deployment in 2008. This module was the center of attention with the most activity. Two octopus resided in it with a tube anemone. 10-12 Triggerfish loitered around and inside this module. 10 Gag Grouper loitered inside and outside this module. One Red Grouper was around this module. It appears that these fish preferred this module over the other three erect/standing modules. It also appeared that the fish preferred the rectangular windows in the horizontal position over the vertical position. One side of the module created a floor and it’s windows became holes that octopus and triggerfish used. With this module on its side, it replicated a small cave environment with a large opening (module’s base/footing) on one end and a smaller opening on the other end (module’s top). It also appeared that fish were more tolerant of divers at this module over the other the other three modules. This may be due the larger horizontal openings presented in this position. See attached photos.
