In one sentence, describe what the following article is about: Larger beardies may be aggressive towards smaller ones, and males tend to be territorial. This is further complicated by the fact that it can be difficult to sex bearded dragons when they're young, so you may not know whether you have a male or female beardie at first. As opposed to a vivarium, which has 3 glass sides and a top, a terrarium has solid walls on four sides with a screen lid. A vivarium can cause too high of humidity levels, which can seriously harm a bearded dragon. Note that the terrarium has to be at least 20 gallons for a baby to juvenile and at least 30 gallon breeders for an adult, though up to a 55 gallon is recommended for running room.  If you're building an enclosure yourself, keep in mind that it must be well ventilated, easy to disinfect, and able to maintain high temperatures (see below). Cages with wooden sides must be sealed with polyurethane or a similar waterproofing agent, and the joints must be caulked for proper cleaning and disinfection. Ensure that fresh polyurethane be allowed to dry several days and air the cage out thoroughly before placing your beardie in it, otherwise toxicity may result. Beardies can grow up to 2 feet (61 cm), move fast, and like to climb, so they need plenty of space in their home. For young dragons, a 10 gallon (39 L) tank is adequate, but this will last them only for a few months, as they grow quickly. An adult dragon requires much more room: a minimum of 55 to 60 gallons (208 to 227 L) is required, but 75 to 120 gallons (284 to 454 L) is preferable.  If you're building an enclosure, make sure it is at least 48 in (122 cm) long, 24 in (61 cm) wide, and 18 in (48 cm) high. To save money, you can purchase a large adult habitat immediately. Consider using adjustable partitions to increase the living space as your beardie grows. Do not use glass, plexiglass or wood to cover your cages. This will not allow enough air circulation and will also trap humidity in the cage. Screen tops ensure there's adequate air flow, allow your lighting and heat sources to work correctly, and also let humidity escape. Ensure that the lid fits tightly. The bottom of the enclosure should be lined with a substrate that is safe for your dragon and easy to clean. It is very important to choose a material that does not put your dragon at risk: beardies often eat bedding made of small particles, which can result in impaction (blockage of the intestines) and death. Use flat newspaper, paper towels, butcher paper, or reptile carpet. These choices are cheap, easy to clean, and pose no health risks to your animal. Make sure that the very bottom of the vivarium is covered with a white or brown unheated mat. This will ensure that if your beardie decides to dig under whatever bedding you placed, its most vulnerable part (its stomach) will not make contact with the cold bottom of the tank. Create an environment where your beardie can climb, hide, and bask – all behaviors that it needs for well-being.  Never use anything from nature. Natural logs and other objects could carry parasites, no matter how much you clean them. Instead, use ready-sterile logs and sticks from stores. Wash them with warm water and let them dry before placing them in the tank. Add some branches for climbing and basking. They should be securely located under the secondary heat source (see Part 3). Make sure they are as wide as your bearded dragon. Oak is a good choice, as are boards covered in carpets. Avoid wood with sticky sap or pitch. Provide some smooth rocks for basking and wearing down nails. Give your beardie a place to seclude itself. You can add an empty cardboard box, cardboard tube, or flower pot. The hiding place should give a snug fit and be placed high in the enclosure. If your dragon doesn't use the hiding space, try moving it to a new location or using a different object. Put in a few plants to provide shade, humidity, and a sense of security. Make sure the plants you choose are nontoxic to bearded dragons (such as Dracaena, Ficus benjamina, and hibiscus). It is important that the plants and their soil have not been treated with pesticides, vermiculite, fertilizer, or wetting agents. Before putting the plant in the cage, wash the plant with a water spray and pour water enough water on the soil so that it drains out the bottom: this helps remove any toxic chemicals. You may also want to keep newly purchased plants in a separate part of the house for a while before introducing them to the bearded dragon's enclosure.
Summary: Note that most beardies are housed alone. Purchase a terrarium instead of a vivarium or aquarium. Make sure the habitat is an adequate size. Use screen lids for the top of the enclosure. Provide flooring. Include some "furniture" in the housing.

Problem: Article: It's not enough to write in your goal journal every day. While the act of writing itself has benefits, you also need to read over those entries on a regular basis if you want to track your progress.  By going back over your entries, you may be able to identify patterns in your behavior that you didn't notice before. You can see how your work towards this goal is impacting other areas of your life. Set aside additional time at the end of each week to go through your entries for that week – just a couple of minutes is all it should take. Then at the end of each month, read over all of your entries for that month. You may want to leave extra space in your journal for thoughts or reflections on your progress at the end of each month. You want your goal journal to exist as a permanent record of your progress towards your goal. As you're reviewing your entries, clean up any mistakes and clarify sloppy writing. You may want to do your initial journaling in a notebook, then copy your entries once a week into a clean computer file. The act of copying your entries also will help you review them and notice patterns emerging in your behavior. Your goal journal may include discussions of sensitive situations, or reveal intimate details about your life. Keep your goal journal safe from prying eyes by hiding it in a secret location or in a locked drawer.  You need to be able to be 100 percent open and honest in your goal journal. You may be less inclined to do that if you are afraid someone else will be able to read it. If you're keeping your journal on your computer, you may want to password protect or encrypt the file so that anyone who accesses your computer won't be able to look at the document. Your goal journal is a record of your progress towards your goal. Even after you've achieved your goal, the journal has information that can help you if you decide to go after a different goal.  Looking back over your accomplishments also can be motivating. If you have a goal you achieved, you can read back through your goal journal when you're feeling a little down to remind yourself of how far you've come. If you're keeping a notebook as your journal, you may want to make a computer file each month, or once you've achieved your goal, to keep as a permanent record. You can either scan the pages or retype them from the words you wrote.
Summary:
Review your entries regularly. Update and rewrite illegible entries. Protect your privacy by locking away your journal. Keep your journals indefinitely.
