The doctor will likely order these tests first to make sure you don't have a stomach blockage. A stomach blockage can cause symptoms that are similar to gastroparesis.  For an endoscopy, your doctor will use a tiny camera on a flexible tube. You'll first be given a sedative and likely a throat-numbing spray. The tube will be threaded down the back of your throat and into your esophagus and upper digestive tract. The camera will help your doctor see what's going on more directly than they can with an X-ray.  You may also receive a similar test called an esophageal manometry test to measure stomach contractions. In this case, the tube will be inserted through your nose and left in for 15 minutes. If the doctor doesn't see a blockage in the other tests, they'll likely order this study. This test is a bit more interesting. You'll eat something (such as a an egg sandwich) that has a low dose of radiation. Then the doctor will look at how long it takes you to digest it by using an imaging machine. Typically, you'll get a diagnosis of gastroparesis if half the food is still in your stomach after an hour to an hour and a half. An ultrasound will help the doctor detect if some other issue is causing your symptoms. Particularly, they will look at how well your kidneys and gallbladder are functioning with this test. If the doctor is having a hard time explaining your symptoms, you'll likely have this test done. Basically, it's a way of listening to your stomach for an hour. They'll put electrodes on the outside of your belly. You must have an empty stomach for this test.

Article: Parrot cichlids can grow as large as 10 inches (25 cm) 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 84 °F (24 to 29 °C). Even blood parrot cichlids, bred in captivity by humans, thrive in warmer waters. Temperatures below 80 °F (27 °C) 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.
Question: What is a summary of what this article is about?
Purchase a large aquarium. Install a large canister filter. Keep a heater in the aquarium. Add the substrate. Provide the fish with hiding places.
