It might be possible for you to feel better about regret if you consider how the situation might have been worse. You can do this by looking at the hardships that other people have suffered and noticing how some people have been worse off than you. For example, you might feel regret about not pursuing a college degree, but perhaps you know someone who got his degree and then could not find work in that field. That person might have suffered even more than you because he was landed with high student loan payments and could not find a job with high enough wages to be able to pay the loans off. Regret has a negative impact on our emotions, but we can also gain lots of positive things through these experiences. Consider what positive aspects came you’re your experience.  For example, perhaps you regret your marriage and wish you had married someone else. But you can look at what you gained from the marriage, such as kids, more self-knowledge, stability, etc. Identifying the positive aspects of some situations can be difficult. You may need to look at things that happened after the experience to find the positive. For example, you may regret driving drunk and losing your license, but perhaps the experience led you to seek help for a drinking problem and you gained new friends and a better outlook on life as a result. Practicing gratitude is a great way to increase your feelings of happiness and satisfaction with your life. Practicing gratitude can also help to relieve stress and other negative emotions. Practicing gratitude on a daily basis may also help you to stop dwelling on your feelings of regret and look at positive aspects of your life instead.  To practice gratitude, try making a list of five things that you are grateful for. The following day, add five more things to the list. Keep doing this every day. You can start your list with basics such as, your health, your family, a place to live, food on the table, etc. As your list goes on, you might try to add less obvious things, such as a good cup of coffee, the sound of birds singing outside your window, or an unexpected phone call from a friend. . If you are preoccupied by regret then you are probably focused on the past and what could have been. Meditation can help you to calm your mind and focus only on the present instead of the past. Try incorporating meditation into your daily routine to quiet your mind when it begins to ruminate on the things you regret. You don’t need to meditation for hours. Even five minutes of meditation every day can make a difference in your outlook on life.

It’s possible your betta will contract a disease or infection at some point in his life span, so be prepared by having medications on hand to treat your Betta quickly and efficiently. Medications can be stressful for your betta and should only be used when you have confirmed your betta has a specific disease or infection and medication is necessary to treat the issue. You can find medicine for fish at your local pet store. Your first aid kit should contain the following medications:  BettaZing or Bettamax: These medications are anti-parasitic, anti-fungal, and anti-protozoan. They are useful for a number of issues, such as fungus and velvet parasites. You can also use this medication as a preventative measure if you are trying to get a Betta used to a new environment or every time you introduce a new Betta to your tank. Kanamycin: This antibiotic can be found at many fish stores and pet stores. It can used for serious bacterial infections. Tetracycline: This antibiotic is used to treat less serious bacterial infections like fungus. Ampicillin: This is a useful antibiotic for treating popeye and other infections. You can find this antibiotic in specialty fish stores and online. Jungle Fungus Eliminator: This is an anti-fungal treatment that works on several fungus infections and is useful to keep on hand as a Betta fish owner. Maracin 1 and Maracin 2: These medications come in hard tablet form and can be used to treat mild infections like fin and tail rot. However, the are not as effective as other medications to treat more serious infections. This will help to remove any waste buildup and any decaying organic matter from excess food and dead leaves or roots from plants. Doing a small partial water change weekly will also clean any toxins from the water and keep the water clean.  Do not remove any of the aquarium plants or decorations from the tank or bowl. Removing or cleaning these items can kill the good bacteria that has been filtering through your tank and reduce the quality of your filtration system. As well, you do not need to remove your fish from the tank or bowl when you do a partial water change. This can stress out your fish and could expose him to harmful bacteria.  You can use a siphon to suck up any gunk in the gravel and decorations. You should also use an algae scraper to remove algae on the surface of the tank or the tank ornaments before you remove any of the water.  If your tank does not have a filter, start with clean water and test daily for ammonia. When the kit says there is ammonia, it's time for a water change.  Getting a top cover for the bowl or a filter can reduce the water changes you will need to do and protect your fish from getting an infection or a disease.  Check the water once a day to ensure it is not cloudy, foamy, or has an unusual odor. These could all be signs of a bacterial bloom and may require you to do multiple 50% water changes. Doing this will prevent your Betta from developing any diseases or infections. Bacterial infections like fin and tail rot can be prevented by keeping up with weekly water changes. Unlike table salt, aquarium salt does not contain any additives like iodine or calcium silicate. (Don't use table salt!)   Do not use aquarium salt or copper-based medicines if your tank also includes aquatic snails or corydoras, as they can not handle these medicines and may die. Nerite snails are salt-tolerant, however they will not be able to handle copper, so proceed carefully.  Always follow the instructions on the package for dosage amounts. Keep in mind that aquarium salt is not for long term use. It's only for baths.
