Problem: Article: Place your cichlid into the aquarium while they're still in the bag. Let them remain there for at least 1530 minutes. Then, gently scoop your fish into a net and into the aquarium. Dispose of the bag water by dumping it down the drain or watering your garden if you have one. Don't let any water from the bag drip into the aquarium. Parrot cichlids are omnivorous, meaning that they'll eat plant or animal products. Proper food includes brine shrimp, bloodworms, tropical flakes, sinking pellets, and commercial parrot cichlid food. Make sure your fish get enough fiber to prevent swim bladder disease. Feed your fish at least twice a day. Choose light bulbs that emit light from the red end of the visible spectrum. Purchase them at pet supply stores or hobbyist stores. Blue light could dull the color of your fish's scales. The lighting shouldn't be too bright, as cichlids prefer darker waters in the wild. Keep the wattage between 0.5 and 1 watt per gallon (4 L). Don't leave the lights on for more than 12 hours per day. Too much light for too long can encourage the growth of deadly cyanobacteria (also known as blue-green "algae"). Change the lightbulbs if they're a year old. A good pH for a parrot cichlid would be between 6.5 and 7.8. Monitor the water and every object you put in the tank. This includes driftwood and other hiding places, as well as the substrate. Rocks that contain too much calcium can make the water too alkaline and can dull your fish's color. Wild breeds of parrot cichlids can tolerate pH levels as low as 4.0 before feeling any health effects. Buy pH testing strips in any pet supply store or big box store. High levels of nitrite and phosphate can contribute to cyanobacteria (blue-green algae), which can kill your fish. To prevent the algae from growing, use separate testing kits for nitrite and phosphate. Nitrite shouldn't exceed 0.1 parts per million (ppm), and phosphate shouldn't go over 0.2 ppm. If the phosphate levels get too high, add a phosphate-removing material to your filter. For high levels of nitrite, clean all debris from the tank with a siphon vacuum. Then, clean out your filter thoroughly. Remove a third of the water in the tank and replace with with clean water. If you notice cyanobacteria growth, install balanced bulbs that emit 6,000 to 14,000 kilowatts. Lower the tank temperature to 76F (24C). Change 10 percent of the water every other day until nitrite and phosphate return to normal. Use a testing kit to measure their levels. Siphon at least 20 to 25 percent of the water in the tank. Aim for 25 percent if you have several fish. Clean any algae growing on the glass and/or in the substrate. Algae can be green or brown when growing on surfaces. Algae blooms occur on the water. Tackle them by: Not worrying too much about green algae growing on decorations. It's generally harmless. Cleaning brown algae growing on the tank, with a sponge or algae magnet. Use a siphon vacuum to remove any algae growing on decorations or the substrate. Recognizing algae blooms. Green, cloudy water is the telltale sign. Replace all of the water. Clean the entire tank and its components thoroughly. Install a diatomic filter to remove any lurking algae and prevent recurrences. Parrot cichlids are rather territorial and will act aggressively toward smaller fish. If you choose to add other fish, consider silver dollars, black skirt tetras, convict cichlids, and other semi-aggressive fish nearly the size of the parrot cichlid. Avoid smaller tetra, angelfish, discus, and ram cichlids.
Summary: Acclimate your parrot cichlid. Give them the proper diet. Control the lighting. Monitor the pH. Test the nitrite and phosphate levels. Clean the tank weekly. Choose tankmates carefully.

Problem: Article: If you want to invent a sport, you'll have to see what kind of balls, rackets or sticks, and goal-type equipment you have. Look around your own house and ask your friends too. Make sure you have enough if each player needs to use their own stick or ball. You might find a golf ball, a baseball bat, a football helmet, and a racket. You don't have to pick up all of the stuff, but at least make a list of what you have. If you have no sports equipment, make a sport that doesn't need any. Use just your body and your environment. Adapt running, hand-to-hand combat, or exercise into a sport. Use non-sports equipment for the game. Look for buckets, brooms, rocks, sticks, chairs, boxes, blankets, or any other household items to somehow use for a sport. Come up with how players score in the game. Have them throw something the farthest, or hit a ball the most times. Make sure you choose if they must reach a certain score, or if whoever has the best score or performance wins. For example, you might have to score the most points to win. You might score by using the racket to hit the golf ball into the helmet from different distances away. The scoring doesn't have to be points. It could be accomplishing a task first, performing a feat best, or doing something the most times. You don't have to make totally new rules for your game, just use the rules of other games you know. Make sure the rules tell players what they have to do and what they are not allowed to do. Combine rules from different sports so they fit together. For example, most sports have boundary lines that players must stay within. If you cross a boundary line, the other player or team takes control of the game. Make rules about players touching each other. Football allows players to make physical contact with regulations about what's acceptable. Yet, baseball has very little contact. Include rules about how to use the equipment, such as kicking the ball in soccer, throwing and catching the ball in football, or tagging the base in baseball. Decide if your game is played one-on-one or with teams, or if it works with either. If there has to be an exact number, make sure you know how many. If the game works with different numbers of players, that will give you more freedom. For example, tennis only works with two players or four players, but basketball works with two to ten or more players. Make sure you have enough space to play. Stay away from buildings and anything else that might get in the way. You'll need room to run around for most sports. Ask your parents before you go away from your house. If you need any type of boundaries or starting lines, use trees or the edge of the grass. If you have cones or rope, use that to set up lines, too.
Summary:
Gather up some sports equipment. Describe how the scoring works. Come up with a set rules for your game. Set a number of players who can play. Find an open place to play the sport in.
