Something is fishy!

I have fish! The other day, I bought an aquarium. It is quite small, only about 15 liters. So far, I have 5 large tetra fish, 10 small tetra fish and 5 neon orange fish (I call them that because I don't know the name.) I am thinking about getting some small shrimp, but I am afraid that they might eat the fish.
I enjoy having fish. Taking care of them is much more fun than I thought. However, I feel so guilty whenever I go out for sushi! (^^;)
