Q: Parrot cichlids can grow as large as 10 inches (25cm) long. For this reason, you'll need to buy at least a 42-gallon (159 L) tank if you want to keep only one fish. Aim for 10 additional gallons (38 L) for each fish if you're planning on giving your fish some companions. Parrot cichlids like to have several hiding places along the bottom of the aquarium, so a taller tank wouldn't help. Parrot cichlids are large fish with healthy appetites. Their tendency to dig in the substrate can stir up dirt and algae. This is why they require a larger filter. A heavy-duty wet/dry filter will help to remove these waste products and keep the water clean. Purchase a filter that can be mounted to the back of the tank. Avoid anything that goes under the substrate, as digging fish can easily disturb its functioning. Many breeds of parrot cichlids originate in warm South American climates. Keep the aquarium temperature about 76 to 84F (24 to 29C). Even blood parrot cichlids, bred in captivity by humans, thrive in warmer waters. Temperatures below 80F (27C) might cause cichlids to become less social. Parrot cichlids like to dig, so make sure the substrate is soft. Opt for fine dark sand, which they can comfortably burrow under. Avoid putting plants in the aquarium, since the cichlid's tendency to dig could knock them over. Parrot cichlids can be territorial, especially if you plan on adding smaller tankmates. Keep broken flowerpots, small rocks, driftwood, or stacked rocks to form caves that provide the fish with hiding spots.
A: Purchase a large aquarium. Install a large canister filter. Keep a heater in the aquarium. Add the substrate. Provide the fish with hiding places.

Article: Scatting is the act of turning your voice into improvisation instrument, removing real words and just focusing on noise, melody, sound, and tone. As such, everyone can scat immediately, even if it feels weird or uncomfortable. Just start making noises that sound great over the song your hearing. Listen to some classic scat singers for early inspiration. "Perdido" by Sarah Vaughan, "Them There Eyes" by Ella Fitzgerald, and Louis Armstrong's "Heebie Jeebies" are all incredible early examples. Scatting is generally a jazz skill, but artists like Scatman and Bobby McFerrin have expanded it to other genres in modern times. You need to get used to your voice not as a speaking mechanism but as an instrument. As you first start, limit yourself to copying your favorite singers. Play a couple bars of scat singing, then try to repeat it back verbatim to start learning sounds, tricks, and melody construction. The blues, with simple chords and built-in call and response, is a great place for beginners to begin. Try out "Centerpiece" by Lambert, Hendricks & Ross. Try mimicking actual sung lyrics, but don't use the words. Practice capturing the singer's melody with random syllables instead of words to get used to scat. As you improve, start copying guitar, horn, and other lines with your mouth, using whatever syllables come to mind to replicate the sound. There is no noise, when scatting, that is off limits! As you begin improvising your own scatted lines, start with a couple of "accepted" scat words and syllables. Simple, percussive noises are the easiest way to start, using sounds like "bob," "beep," "ski," "do," etc. Remember that you're not trying to say anything. You're playing with musical notes, not words. The musical scale made famous in "The Sound of Music" is a great place to start: do, rey, mi, fah, soh, la, ti, do! Scatting is about using your whole body to make noises and sounds, improvising more than just syllables. As you improve and get more and more used to scatting, start playing with the following variables to expand your musical vocabulary as you sing. Volume-- draw the audience in by going quieter, then build back up to a louder crescendo with bigger, louder syllables. Tone-- how do you sound with you chin tucked in? You chest puffed out? How does the shape of your mouth change the sound of your singing? Pitch-- perhaps the most important, pitch is how high or low your notes go. As you get used to making up syllables on the spot, start working on varying pitch with each word. Songs get boring when they stay in the same pitch for too long -- give some melodic variety. Scatting is an intensely rhythmic art form -- you voice is both percussive (like a drum) and melodic (like a trumpet, piano, etc.). As such, you must be able to stay in time while you improvise, holding to the beat like any other instrument. While good singers should already feel comfortable with this, newbies must practice with a metronome or backing track to get used to staying on time at all times. Always start at a speed you can keep up with comfortably. While you can set any rhythm you want, most scat is over a 3/4 "swing feel" of jazz. That said, practicing improvising syllables on the spot without music or metronome is still a valuable skill. You just need to train your ear so that you can snap to a backing band when the chance arises.
Question: What is a summary of what this article is about?
Use improvised syllables and sounds to scat over instrumental tracks. Practice "call and responses" with scat singers and instrumental lines. Start with simple, rhythmic syllables, focusing on melody instead of new sounds. Accent, modulate, and have fun with your syllables. Practice with a metronome or an instrumental track to ensure you stay on time.

Q: Once you are finished adding features and filling out content, you can build the app so that it can be ran on your Android device. The process will vary depending on what program you are using. If you are using an online app creation program, you may have to wait a few minutes for your app to be constructed by the program's servers. You are generally provided with an APK file that can be downloaded onto your device. You will need to set your device to allow installation from unknown sources. You can allow this from your device's Security menu. Some app creation programs will email you the link to your app that you can open from your phone. Once you've installed the app on your device. Test it out to ensure that it is functioning properly. Send the APK file to some friends and family so that other people can help you test it. You are more likely to catch bugs and problems if you have more people looking at the app. Try to do things during testing that the app isn't made to do. This will help you find ways that your users may accidentally break your app. After you have tested the app for a bit, fix any errors that you come across or anything that doesn't work as well as it should. Your app should be easy to navigate above all else, so ensure that your app flows smoothly from one task to the next. Your publishing options depend heavily on what program and package you signed up for when choosing your creation software. If you chose a free service, your app will most likely be ad-supported, and may only be available through that company's app store. More expensive options allow you to publish directly to the Google Play Store and may even include promotion and marketing. Consider releasing a free version with ads and limited functionality and a paid version with no ads and full functionality. This is one of the most common ways to monetize a mobile app. Make sure that your app has a good description and accurate tags. These tags will help users find your app through relevant searches, and are essential if you want your app to succeed.
A:
Build the app. Test the app. Fix any errors. Publish the app.
