A young boy set up an aquarium containing 120 liters of water and six fish. The capacity for the aquarium is ten fish. By the end of the first year, four fish were added to the aquarium and two of the original fish died. The aquarium was cleaned according to instructions received from sales people, however cleaning was skipped in the last two months of the first year. In the first two months of the second year, three more fish died. No other changes occurred for the remainder of the year. What was the initial density of fish per liter, to the nearest hundredth? (Base your calculation on the number of fish right after the aquarium was set up.) 1 point
