    Beginner Freshwater Aquarium
    I am a new member and recently got an aquarium, all week the fish have been fine. Today however almost all of the fish were swimming directly under the top of the water at about a 40 degree angle. After i noticed this i changed the water and they all started their normal swimming patterns again...
