Well I was at my local petsmart holding adoptable dogs, and I had to go check out all their animals' conditions. I was really impressed until I came to the fish. They had somehow managed to cram 1 guppy, FOUR feeder goldfish, a black moor goldy (with ick) a male betta, and 2 female bettas in a HALF GALLON display tank. All fish were smaller then usual size (the male betta was the largest at about 1.5"), but they had no room whatsoever to move around. I had no idea how they were alive in there. I spoke to the manager and she proptly told me that they had been in there all day and none had died so it was perfectly ok. on their tanks that they sold the fish in, it even stated that goldfish needed atleast 2g and guppies atleast 1 (which are both too small, but still larger than what they were in) I was completley outraged that they would encourage people to put so many fish in something so small.....
