Fishkeeper — a fishkeeping simulator with management elements, inspired by the The Sims 3 series. Starting with the purchase of your aquarium and equipment for it, you can grow your fish, snails, shrimp, and many other aquatic inhabitants. As in other life simulators, you will need to monitor the condition of your wards: feed them on time, check the water temperature and salinity, clean the aquarium from dirt, and much more. When the fish grow to a certain stage, the option to sell them becomes available, and particularly valuable specimens should be put up for auction. The funds received can be spent on further development of the biosystem and its replenishment with new inhabitants. The game also offers the possibility of traveling through the aquarium via a small drone-bathyscaphe, allowing you to enjoy the inner world of your creation.
