OK,I decided to get a fish tank to dress up the ole place and read i'd need fish food.Got it,but how do i use it? I can only seem to put the deed target away from the tank,not in it.Is it ok to have it close to the tank's? When i try to "use" it,by clicking it,nothing happen's,and i can't pick it up either.So,how do i keep the fish fed?
