Well actually, three fish and a crab. After I came back from Japan my brother and parents told me our 20 gallon tank was a mess and indeed it was! The water was solid green, there was this weird poopy stuff on the bottom, and bugs were swarming in the water. The environment was completely polluted. I dumped out the water in the toilet and it made me throw up in my mouth because the smell was so bad. The fish were too large to flush down the toilet so we had to drop them in the gutter... they made big splats and it was sad since we had one of them for four years. But we liked them all a lot!
