Gramma has a huge fish tank at her place, set down into the floor like a pond. It is the size of most living rooms, with a smooth rounded kidney shape, like a modern swimming pool. On the bottom there are many colorful corals and rocks, and many different types of fish swim in little schools here and there. Gramma sits to the side of it in her wheelchair.

I think I get into the pool to get a better look at the fish. I'm mostly interested in these brownish spotted fish that are very fat and round, sort of like a puffer fish, like those I saw at a Chinese restaurant a few days ago. I saw them once, but I can't seem to find them again.

I seem to be helping her clean the tank. I have a big tub, like a half gallon, of some sort of chemical, but I'm not sure if I'm supposed to pour it in the fish habitat or if it's laundry detergent or something.
