They are beautiful. Make me want to get myself a) a new polariser (still crying :cry: over the loss of mine in some wilderness back in February :cry: ) and b) go to an aquarium with camera in tow myself, too!!!
cool shots, i love the colors, movement, and symbiosis in the first shot... cool capture of that guy in the second, although the DOF appears just a tad narrow with his eye a little blurry. I agree with tpe about it being tough to get shot in an aquarium... good job. i never got any good ones when I still had mine...
