Resident of the soda-can

Our trash is littered all over the sea beds, polluting them more and more. Fishermen from the gulf of Mexico have been reporting fish catch with oil in guts. Nature is very adaptive so wild life continues to live under the blessings of BP as well. Some times our wastes like the soda-can in the image is a blessing.
This tiny goby has taken residence in a soda can and seems to be decorating its facade, a tiny coral buildup maybe..
