I had what’s called a fish eating decoy muscle, and it was difficult to keep them alive, but that was a cool invertebrate. In subsequent years, we developed a standing exhibit within one of the galleries to highlight invertebrates. Then we also developed a coral and a exhibit within a another gallery. So the, the collection grew. But when I started there, it was pretty bare bones, not, not a lot of sophisticated equipment. We depended on the gravity tank for circulation, which meant water eventually was pumped to tanks above the public space and flowed by gravity down to the exhibit and reserve tanks. That’s thus the name gravity tanks. The salt water that we used at that time was a recipe that Roger had developed.
