I started out with a simple big glass jar, with some rocks in it, some waterplants, and a couple of shrimp I bought in the shop. They survived for a very long time, and I spend more and more time simply zoning out, and watching the shrimp. Just 5 minutes of shrimp watching a week works wonders to relax your mind.
After a long time I encountered a very nice square aquarium in a pet shop, and I just went for it. I bought the square aquarium and some plants, a bag of little rocks and a bag of soil, and started preparing the move. Setting up the new aquarium was easy. Soil, rocks on top. A bit of water and add the plants. A few big rocks and some big shells as decoration, and flll up the aquarium to have it half full. Wait one day, and finish the aquarium. Add the original shrimp water, add the shrimp, test the pump, test the lighting, and done.
Our shrimp are flourishing. Since I have been giving them some extra fishfood to eat, they have exploded in number. There are now around 60 shimp in the tank, and I give them new floating plants every couple of months, which they seem to love. In addition they sometimes get some dried leaves, of small pinecones, or even small squid skeletons (for the calcium).
