Which of the containers shown below will continue to have healthy fish and plants at the end of a week?
A 
B 
C 
D None of these
Well actually, the *container* is too small for 3 fish. Those look like saltwater fishes, how do i know that water is mixed with salt. Saltwater fishes usually require tanks that are 10 gallon upwards for each fish, that one looks like 5 gallons. And to add, the fake plant, could hurt the fish if they graze against it, its not real because there is no substrate.
