The Fishy 2000 is a modern fish tank that will work in space or on any chosen planet that has been made fit for human habitation in the year 2050. Astronauts need fresh food, and fish is healthy source of protein. What makes this work in space so well is its special plexi-glass slot and its ability to have a slide-on food holder to feed the fish. This fish tank is made for all smaller fish but, may work best for a fish like a Yellow Perch. Also, the most appropriate food might be something as simple as bread crumbs. The Fishy 2000 was made to hold fish that can eat human leftovers, so there is not as much waste left on the planets, or in the space station.
