Article: Goldfish, Rosy Barbs, and Guppies are excellent starter fishes. Before you buy your tank and other supplies, determine what kinds of fish and how many fish you will have in the tank. This way, you can buy an appropriate sized tank and the appropriate gravel or substrate. It is recommended that you buy a large tank instead of a small tank. Larger tanks are easier to clean, and you can add more fish to larger tanks. Avoid common myths that tell you it is acceptable to keep fish in bowls. Larger tanks also allow your fish to grow while still being comfortable. Keeping fish in an overcrowded tank is the fastest way to reduce water quality and introduce toxins and diseases to the water.  It is recommended that you start with a fish tank that can hold between 20 and 55 gallons. For smaller fish, use a tank that can hold around 10 gallons. It is also better to buy a wide tank instead of a tall tank. Wide tanks have more surface area, and thus, allow more oxygen to enter the water and more waste gasses to escape. Gravel, or substrate, comes in various sizes, colors, and forms. You can choose from gravel, sand, or crushed coral. Gravel is the most common form of substrate and comes in small to large sizes. It is recommended that you buy gravel that is medium in size.  Do not buy gravel with sharp edges. The sharp edges can harm the fish's scales. Fish that like to pick up the gravel or dig into the gravel are especially at risk. Sand substrate is great for fish with delicate barbells, such as the Corydoras catfish. However, it is very difficult to clean and can get stuck in your filter. If you have a picky eater, like a puffer fish, it might swallow the substrate. Crushed coral gravel is great for fish that prefer a higher pH, such as African cichlids, as this reflects on their natural habitat. There are three different types of filtration systems: external, internal, and under gravel. However, whichever you choose, make sure it is high-quality. Internal filters are great for small tanks.  Under gravel filters move the water through the gravel, which induces biological filtration to occur. They pull water in and they release it out of the spout. Examples of high-quality filters are the Fluval External filter, Penn Plax Cascade canister, and the EHEIM Classic External canister. There are a variety of decorations you can choose from. There are aquarium backdrops, rocks, driftwood, plants (both real and fake), and furniture or decoration caves, tunnels, and bridges. Make sure to purchase a variety of decorations. A starter kit tank though comes with a rather childish decor, as it is marketed toward children.  Plants and furniture allow your fish to hide out, feel safe, and relieve stress. However, for more greedy, herbivorous fish, make sure to get more sturdy, nip-proof plants. Aquarium backdrops are great for hiding cables and equipment behind the tank. They also create an illusion of depth for the fish. Make sure the decorations you buy are safe and non-toxic sharp objects are harmful to fish, especially to the Eye goldfish and the Black Moor fish.

Article: Multiply the total width of the accent wall by the height of your ceiling. This tells you the square footage of the accent wall. Typically, 1 gallon (3.8 L) of paint covers around 350 to 400 square feet. Divide your total square footage by 350 or 400 to figure out how many gallons of paint you’ll need to cover the wall. A single gallon is enough for most walls, but keep in mind you’ll probably need to do 2 coats.  If there are windows on the accent wall, subtract 15 square feet from your total square footage. Then divide that number by 350 or 400. If there's a door, subtract 21 square feet before dividing by 350 or 400. Take off the outlet covers, fixtures, switch plates, and window coverings before you get started. Use painter’s tape to mask off the window sills, door hinges, baseboards, etc. Protect the floor with a tarp and cover any furniture in the room. Crack a window or get a fan so that the room stays ventilated. Since the color of the accent wall will contrast quite a bit with the ceiling and other adjoining walls, it’s important to get a straight, clean line where the accent wall meets them. Crooked or smudged lines will be very noticeable. Apply the tape slowly and be precise for best results. Dirt and debris will prevent the paint from adhering well to the wall, so always clean interior walls before you paint them. Create a mild cleaning solution with warm water and a few drops of dish detergent. Wipe the wall down with a sponge or cloth, working from floor to ceiling and in small sections. Let the wall dry completely before moving on. Primer isn’t required, but it’s recommended. It will help the paint adhere to the wall, allow for better coverage, and help the paint wear better over time. Buy an indoor paint primer and apply one coat to the accent wall with a roller or paintbrush. Let it dry completely before you start painting. Use a latex-based interior paint for this job. Start applying paint in one of the top corners, working from the ceiling to the floor in small sections. Use an angled brush to get into the corners, then switch to a roller to cover the main wall space faster. Use the angled brush anywhere you need to do detail work.  Wait for the first coat to dry, then apply a second coat the exact same way. Let the last coat of paint dry completely before removing the painter’s tape and replacing fixtures.
Question: What is a summary of what this article is about?
Calculate how much paint you’ll need. Remove the fixtures on the wall and put down protective tarp. Use painter's tape to create clean lines on the adjoining walls. Clean the wall before you paint. Brush on a coat of primer for the best paint coverage (if desired). Apply 2 coats of your chosen paint for the best finish.
