In one sentence, describe what the following article is about: Keep the fish flat on the surface, but grab hold of the tail so it won't slip around when you start removing scales. You may want to put on a pair of disposable gloves to protect your hands. Scales and fins can be sharp. To remove scales, use the blunt edge of the knife instead of the sharp edge. Hold the blunt edge at a 45 degree angle. Place the blunt edge right up against the fish's skin near it's tail fin. Rake the backside of the knife along the side of the fish, moving from its tail to its head. Make long, even strokes. You'll need to apply a little pressure, but not much. As you scrape, the scales will start popping off. It's going to get a bit messy! Continue until that side of the fish has no remaining scales. Flip the fish over and repeat on the other side. After you have removed all the scales you can with the knife, hold the fish under cold running water. The water should help get rid of any scales that are still on the fish. Keep rinsing until no scales remain.
Summary: Hold the fish firmly by the tail in your non-dominant hand. Take a knife in your dominant hand and turn it to the blunt edge. Scrape the side of the fish from the tail to the head. Rinse away any remaining scales with cold water.

Angina is chest pain that can feel like a slight pressure, a burning, or a fullness. It is often mistaken for heartburn. Angina can be a sign of coronary heart disease, which is the most common cause of heart attacks. If you feel any type of pain in your chest, it's best to get it checked out right away. Most angina pain occurs in the chest. However, it may also occur in the arms, shoulders, neck, jaw, throat, or back. It may be hard to tell exactly where you're feeling the pain. Angina pain usually gets better once you've rested for a few minutes. If your chest pain lasts for more than a few minutes or doesn't improve with rest or angina medication, seek emergency medical assistance. Some people experience angina after exercising, and it's not always a sign of disease or a heart attack. A change in normal patterns is the most important thing to watch for. If you have what you believe to be painful indigestion, you may actually be experiencing angina. Make an appointment with your doctor to determine the cause of the pain. Arrhythmias are abnormal heart rhythms, and they're present in at least 90% of people who have heart attacks. If you have a fluttering feeling in your chest or feel like your heart "skipped a beat," you may have an arrhythmia. See a specialist who can conduct testing to determine the cause of your symptoms. Arrhythmia may also display more serious symptoms, such as dizziness, lightheadedness, fainting, rapid or pounding heartbeat, shortness of breath, and chest pain. If you experience any of these symptoms with arrhythmia, seek emergency medical assistance. Although arrhythmia is very common, especially in older adults, it can be a sign of severe medical issues. Do not simply ignore an arrhythmia. Consult with your physician to be sure you do not have a more serious condition. In older people, these symptoms may actually be a sign of heart problems. Seek medical attention if you experience unexplainable cognitive difficulties. Women are more likely than men to experience unusual, sudden, or unexplained fatigue as a symptom of heart attack. This fatigue may start a few days in advance of an actual heart attack. If you experience abrupt, unusual fatigue without having changed your daily activities, talk with your doctor immediately.

One-sentence summary -- Seek medical attention for angina. Determine whether you have an arrhythmia. Be aware of disorientation, confusion, and stroke-like symptoms. Look for unusual fatigue.

Problem: Article: Gray tree frogs thrive in high humidity levels, so it's important that you keep your frog's aquarium humid by lightly misting it with water once a day. You should also lightly mist your gray tree frog with water since gray tree frogs stay hydrated by absorbing water through their skin. To mist your frog and its tank, you can use a mist spray bottle filled with spring water or dechlorinated water. Regular cleanings will help prevent your frog from getting sick. To clean out its aquarium, carefully transfer your frog to a separate container that it won't be able to escape from. Then, replace the substrate at the bottom of the tank with fresh, clean substrate, and remove any uneaten insects and debris in the tank. Next, take out the perches and any fake plants and scrub and rinse them with water to clean them off. You should also replace the water in your frog's soaking dish with fresh spring or dechlorinated water. Finally, wipe down the inside of the tank with paper towels. Avoid using any cleaners other than water since they're not safe for gray tree frogs. Generally, it's best to only handle your gray tree frog if absolutely necessary, like when you're moving it to a separate container to clean its tank. When you do handle your frog, it's important that you wash your hands first so you don't transfer any oils or potentially toxic substances to your frog's skin. You should also wash your hands after handling your frog since gray tree frogs secrete a toxin that can cause extreme discomfort if it makes contact with your eyes, mouth, or nose, as well as any cuts or abrasions you have. All captive amphibians are susceptible to health issues that can range from nutritional deficiencies to infectious diseases. Therefore, it's important that you intervene immediately and bring your frog to see a vet if you think there's something wrong with it. A vet should be able to determine what's wrong with your frog and prescribe the right treatment plan. Some common warning signs that there might be something wrong with your frog that you should keep an eye out for include: Inactivity Weight loss Bloating Blotchy skin Cloudy eyes Swelling
Summary:
Mist your gray tree frog and its aquarium with water every day. Clean your frog's aquarium once a week. Wash your hands before and after handling your frog. Take your frog to a vet if you notice signs of health problems.
