i was standing in line at PETCO when i noticed the man in front of me was holding a saltwater fish (some sort of hawkfish, i think), so i asked him what size aquarium he has: 120 gallons. i was so amazed. A wave of jealousy immediately surged through my body....saltwater fish are the coolest!!!!! I just want to say that people with saltwater aquariums are among the luckiest people in the world....
