Before adding your fancy goldfish to the tank, you need to test the tank. Get a pH testing kit, such as the API Master Test Kit, to test the nitrate, nitrite, and ammonia levels. The water should have under 20 nitrates, no nitrites, no ammonia, and the pH level of the tank should be around 6.5 to 8.25. Place the bag of water your fancy goldfish is in directly into your tank filled with water. Wait around 30 to 45 minutes for the water temperature of the bag of water and the tank to be equal. Do not leave your fish in the bag for too long otherwise it could suffocate. Carefully open the bag and let the fish swim out and into the tank water. The water in the tank and the water in the bag will mix together, which will help the fish adjust. Large goldfish may eat smaller fish, which can be dangerous for the larger fish because they will overeat. Get the same type of fancy goldfish to make feeding and care easier. Do not put betta fish and goldfish in the same tank. They have different living requirements and betta fish can be aggressive. Your new fish might have diseases that could infect the fish you already have in your tank, so it is important to quarantine new fish before introducing them to your old fish. You can keep your new fish in a separate tank for two to four weeks before adding them to the main tank. If you want to add another species that is not a fish, such as a loach or snail, choose something that gets along well with fancy goldfish. Make sure to choose a species that does well in cooler water and that the goldfish won't eat. Dojo/Weather Loaches get along well with goldfish and also prefer cooler water temperatures. Get loaches that are at least two inches long so goldfish won't eat them. Rosy Red Minnows/Fathead Minnowsdo well in unheated goldfish tanks, and usually get along with goldfish, but they can get aggressive and attack goldfish who come near their nest. White Cloud Mountain Minnowsare very peaceful with goldfish, but their small size means that sometimes goldfish will eat them. Zebra Daniosdo well with goldfish if there are at least six of them in the tank, but sometimes large goldfish will eat them. Snails can do well in goldfish tanks if the tank is not too cool; however, goldfish tend to eat them.

One-sentence summary -- Make sure the tank is safe for your goldfish by testing the water. Put the goldfish in the tank in the bag it came in. Buy dividers to keep small fish away from large fish. Get a quarantine tank to make sure your new fish is healthy. Add other water species that get along with goldfish.

Q: Jogging on an uneven trail can be a great workout, but it's going to be tough if you're new to running. When you're getting started, stick to flat surfaces like paved roads or running tracks. Tracks have the advantage of being softer than regular roads or sidewalks, so there's less impact on your feet, knees, hips, and spine. Look for a spot that has good visibility and try to avoid secluded areas. Try to pick an area that is familiar to you and gets a lot of foot traffic. This will reduce your risk of injury or attack while you jog. Ideally, you should run with a buddy. That way, you'll have someone with you in case something happens. If you do run after dark or in low-visibility conditions, wear bright clothes so it's easier for drivers, cyclists, and other runners to see you. If the weather is severe or outside air conditions are unsafe, running indoors can be a great alternative to an outdoor jog. Head to your local gym or fitness center and hit the track or treadmills if you don't want to jog outside. Running outdoors can provide a better workout, since you're working against wind resistance. However, you can compensate for that by setting your treadmill on a 1% incline. To reduce your risk of repetitive motion injury while running indoors, vary your speed from time to time (as well as your incline, if you're running on a treadmill). If you're interested in keeping track of how far and how fast you jog, as well as how many calories you're burning, running apps can be very helpful. Many of these apps also allow you to set a route ahead of time, which can be especially useful if you're running in a new or unfamiliar area. Install one of these apps on a smartphone or fitness tracker and get familiar with the features before you start jogging. Some popular running apps include Runkeeper, Map My Run, Runtastic, and Pumatrac.
A: Run on an even, level surface when you're starting out. Jog in a familiar, well-lit area to stay safe. Choose an indoor track or treadmill to avoid the elements. Use a jogging app to plan your route and track your run.

Article: While picking sheets that fit well won't automatically stop them from popping off, it can help. Start by measuring the depth of your mattress. When you look at sheets, make sure they fit the mattress you have, as you may need deeper or shallower sheets, depending on your mattress. If your kids are constantly pulling their sheets off, you may want to switch to zipping sheets. The main part of the sheet goes under the bed, but you only put it on once. The top of the sheet zips off, so you can change it out as needed. With the zipper, the sheets stay in place. For adults, try drawstring sheets, which allow you to tighten the sheets on the bed underneath the mattress. You may have seen the corners that you place under rugs to keep them from moving. You can also use these for your sheets. Place 1 under each corner of the mattress, and then put the sheets on as normal. The stickiness of the corners keep the sheets in place. Foam can also work for this purpose. Sometimes, if you have silk sheets or other smooth sheets, they're more likely to pop off. Try placing a rougher sheet underneath the fitted sheet, such as a flannel sheet, to help keep the top one from popping off.
Question: What is a summary of what this article is about?
Pick the correct-sized sheets. Use zipping sheets for babies and kids. Place non-slip rug corners under the mattress. Place a rougher sheet underneath the softer sheet.
