Remember, you need 10 to 20 gallons of water per fish. If you add a new fantail goldfish to your tank, you will need to increase the tank size accordingly. If your fish feel overcrowded, they may become aggressive and fight with one another. Even in a properly sized tank, some goldfish are simply more territorial than others. If one fish seems to be consistently chasing another, invest in a tank separator to manage conflict. You can buy a tank divider at a pet store. Install it in your tank so your fish cannot get to one another. You can also buy a new tank altogether to correct this problem. Uneaten food at the bottom of the tank can be a problem. Not only does this indicate you're overfeeding your fish, this could cause tank contamination. If you notice un-eaten food during a routine water change, remove it from the bottom of the tank. In the future, cut back on how much you're feeding your fish. Fantail fish can survive in a variety of temperatures. However, sharp increases or decreases in tank temperature can shock your fish's system. Take steps to assure the tank temperature remains relatively stable. Do not place a goldfish tank near a window. The air from outside can cause the tank temperature to rise or drop quickly. Keep the tank in an area of your home where the temperature is stable. Watch for areas of the home prone to drafts, or that get warmer or colder during certain times of the day. You should also quarantine any fish that appear unhealthy. This not only prevents the spread of disease, but allows you to closely monitor the sick fish and treat the illness without harming the other fish, plants, and invertebrates in your tank with medicines and chemicals. Signs of illness can include: Bloated body Listlessness White spots on the body Rapid breathing Bulging eyes Hiding in the corner

Summary: Avoid overcrowding. Consider a separator if the fish become territorial. Watch for uneaten food at the bottom of the tank. Keep the tank temperature stable. Watch for signs of illness.

Tanning is often considered a sign of health, beauty, or the ability and the time to spend time in the sun. Tanning is, however, associated with skin aging and skin cancer. It is also important to understand that tanning does not protect a person from sunburn. If you are going out into the sun, wear sunscreen, especially if you are trying to avoid more getting more of a tan. The American Academy of Dermatology recommends a broad spectrum sunscreen with UVA and UVB protection, and that is at least SPF 30 or higher. The sunscreen should also be water resistant. Some exposure to the sun allows the skin to manufacture an important vitamin, vitamin D. To get the right amount, you should get moderate exposure of the face, arms, legs, or back from the summer sun for about five to 30 minutes. This can be done between the hours of 10 AM and 3 PM at least twice a week without sunscreen if you have darker or already tanned skin. If you are lighter skinned, avoid getting into the sun during peak hours and instead allow some moderate exposure to the sun outside of the peak sun hours to supply the needed Vitamin D without significantly increasing the risk of skin damage or skin cancer. The New Zealand dermatology association suggests that lighter skinned individuals can spend five minutes in the sun before 11AM and after 4 PM, which are the peak sun hours. Because of the light tone of their skin, lighter skinned individuals achieve healthy levels of Vitamin D during this time period. Darker skinned individuals can spend 20 minutes outside the peak hours and achieve healthy levels of Vitamin D. The American Academy of Dermatology does not recommend any sun exposure other than the incidental exposure you might get by getting your mail, walking your dog, going between your parked car and your office, or any other normal, everyday activity. Sunscreen does decrease the amount of Vitamin D production, but the benefits of protecting the skin are important to understand. Since there are so many guidelines and issues surrounding sun exposure and time in the sun, you can get your Vitamin D from other sources and avoid too much sun exposure. There are also food sources of Vitamin D, including fish and fish oil, yogurt, cheese, liver, and eggs. You can also try other foods and drinks that are fortified with Vitamin D, such as breakfast cereals, milk, and juice. When dealing with your skin and the sun, it is important to understand the risks of skin cancer so you can avoid them as much as possible. If you think you have skin cancer or might be at a high risk, talk to your doctor immediately to get tested or learn the best preventative measures for your particular case. Risk factors that increase your chance of skin cancer include: Fair skin A history of sunburns. Excessive sun exposure Sunny or high-altitude climates Pre-existing moles The presence of precancerous skin lesions A personal or family history of skin cancer A weakened or suppressed immune system Exposure to medical radiation Exposure to certain cancer-causing substances

Summary: Learn about suntans and sun exposure. Get the right sun exposure to help vitamin production. Consume more vitamin D. Notice the risks of skin cancer.

Balancing on one foot, especially while moving parts of your body at the same time, will helps you continually adjust to keep your body weight balanced. Stand with both feet together. Raise one foot a few inches off the ground. Stand like this for a few seconds with your eyes open. Then close your eyes and continue to hold the pose. Repeat on the other side. Do this set about 5 times every day. For this move, your arms will swing around like the hands of a clock while you balance on one leg. Stand on one leg and look straight ahead. Put your hands on your hips. Raise one arm up to the 12 o'clock position, then start to move your arm around to the 3, downward to the 6, and over to the 9. Repeat with the other leg and arm. Try to move as little as possible except for your arms. Breathe evenly and concentrate on keeping your body still. Your trunk is the core of your body, and practicing balance with a focus on your trunk will help you stabilize your body and improve your balance. To do trunk turns, stand with your feet just more than shoulder-width apart. Stand on a mini trampoline or other surface that is somewhat squishy or malleable. Hold a heavy item in your hands, such as an exercise ball, a weight, or something similar. Turn your body at your waist to one side and then the other about 10 times. Make the movement a smooth and deliberate motion, but don't swing back and forth. You want your body to work for every twist of your trunk. Don't use the momentum of the twist to propel you into another twist. This exercise requires your legs to be very strong and able to balance while you lift a weight upwards. To do this exercise, balance on your left foot and keep your left knee slightly bent. Bend forward at the hips and touch the ground with your right hand. Hold onto a 5-pound weight with that hand. Raise your right leg behind you. Move smoothly back to an upright position. Repeat with the other leg. Do up to 5 sets of this exercise a few times a week. Practice doing this movement in one clean, smooth motion. Try not to wobble around. Breathe evenly and focus on engaging your core and leg muscles to keep your movement deliberate.
Summary: Balance on one foot. Try the one-legged clock with arms. Do trunk turns. Do a single-leg dead lift.
