Problem: Article: Fresh and clean water is an absolute must to your piranha’s health. Replacing 10-20% of the water every week and cleaning tank walls and gravel can prevent a compromised immune system and also odor. Weekly maintenance shouldn’t take more than 10 minutes.  Write a schedule for yourself to clean the water at the same time each week so that you don’t forget. Clean the aquarium more often if you notice excess waste—remember piranhas are messy—or odor. Be aware that you shouldn’t remove your piranhas from the tank if at all possible. Remember that piranhas generally attack when they feel threatened or are hungry. Protect your hands with a pair of heavy gloves when cleaning. If you absolutely have to remove your piranha from the water, place a bucket or large fish net in the tank and quickly place your piranha in a separate tank. Use a water changing device, or python, from a local pet store for best results. These hook up to a sink and make it easy to clean the tank. This can also minimize the risk of your piranha becoming aggressive with you. If you don’t have a water changing device, gently remove each piranha and put them in a separate holding tank while you clean. This will allow you to clean the tank without stressing your fish or getting injured because the piranhas are stressed. Vacuum the gravel and remove any waste while using the water changing device or when the tank water is low and no piranhas are in the tank. The health and lifespan of your piranha is dependent on high water quality. Ensure proper pH and oxygenation by testing the tank water after every cleaning.  Test tank water with a test kit that you can get at large retailers and pet stores. Test to figure out potential problems like low oxygen, high ammonia, and acidity.  Fix any problems with the water. The pH level can range from 5.5-8.0. Use a chemical neutralizer to restore the pH levels if they are off. Oxygen saturation should exceed 70%. If it doesn’t, you may need to replace your filter or filters. Use a thermometer to make sure the temperature is between 75 and 80 degrees Fahrenheit. If necessary, turn up the heater until you reach the optimal temperature range. Piranhas produce a lot of waste, which can also affect the water quality. Make sure you have a very strong filter or several small filters to stagger maintenance. If tank water gets dirty quickly, consider replacing your filters. Smell the water to see if it has a foul odor. This is a good sign you need to change the filters.
Summary: Clean the tank weekly. Maintain high water quality. Check the filters.

If your email is formal, sign off with something like “Best regards,” or (for an even more formal touch) “Sincerely.” For less formal emails, you may be fine using something like “Take care” or “Cheers.” If you’ve had previous emails from the person you’re writing to, you might look at their sign-off and match your tone to theirs. For example, if they tend to sign with something like “Warm regards,” you should sign off with a similar level of formality. Like the closing sentence, a sign-off can also reflect the purpose of your email. For example, if you’re making a simple request or briefly expressing gratitude for something, you might use a sign-off like “Many thanks,” or “Thanks so much,” followed by your signature. Unless you know the person you’re writing to very well, avoid anything too slangy, informal, or affectionate. In general, things like “Love,” “XOXO,” or “Hugs” should not be used in business emails. If your email is part of a long chain, or if you’re trying to communicate something very briefly and quickly to a co-worker, it may not be necessary to include a sign-off at all. If you don’t feel comfortable skipping the sign-off altogether, a simple sign-off like  –Bernice or –B. should be just fine for brief, informal emails.
