Blinkclick Games just announced their latest "Sims in an aquarium" game going by the name of Fishkeeper. In Fishkeeper, you will play the role of a hobbyist that is looking after an aquarium. You will buy your own tank and equipment. You will select which fish you will take care of and, in real time, you will care for those fish as if they were really there.
The game will eventually offer a range of freshwater and saltwater species...
