I've just been re-reading this whole thread. A few comments (really trivial ones): It is possible Brad Anderson had a tank fail too, but I do know that Larry had this happen in his town house. It was a large tank. Wow, what an awful mess that must have been! I don't think this is what got him out of the hobby - I think he just ended up having other interests (a boat as I recall) taking precedence. (Incidentally, I still have a 70 gallon tank in use that I bought from Larry, including a nice looking wooden stand and hood that he built.) Actually, Shaun's huge clam was a gigas, though I think he had some large clams of other species too (I'm pretty sure there was at least one crocea, for example, and at least one derasa, and maybe others, though I barely knew giant clams back then and the only one that fully registered in my memory was the huge gigas). I could hardly believe that gigas clam when I saw it. And I remember it being a very nicely colored one (I remember its really nice olive green color, and I imagine it also must have had blue spots). I later had a gigas clam that I was given by another member who was taking down a tank - mine had a lot of blue spots, but I remember the background green color being nicer on Shaun's clam.
