When you go somewhere that is not in competition with your business, consider if they are complementary to your business. That is, do they go hand in hand with what you do? If they do, ask if you can leave some business cards. In return, tell them you'll take some of theirs for your business. For instance, an all-natural juicing bar and a vegan restaurant might be considered complementary. Consider carrying cardholders, as well so the business will have an easy way to display them. This step can also work with your friends and family or with people who simply love your service. Ask them if they'd be willing to recommend you, and if they are, give them some cards, as well as letting them know the best way to present you to people. You never know when you'll run into a situation where you'll need them. Keep extra in your car or briefcase, but always have a least a few in your wallet or purse. When someone asks, you'll have something to hand them. While networking events are best for handing out business cards, it's fine to hand them out when you make a connection elsewhere, such as when you're in line at the grocery store. However, the same rules apply. You should only hand them out if you've made a connection, and the card is relevant to the conversation. For instance, if the person in front of you starts talking about the pretty dog on the cover of a magazine, it's fine to strike up a conversation. If you're a dog groomer, that's a perfect opportunity to work in a business card. The Chamber of Commerce will often have a place for you to leave business cards. Visit or call your local Chamber to find out if they offer this service. Many restaurants and businesses have community boards where you can tack up information. Try leaving a few business cards up on these boards. For even more incentive for someone to take one, try having a discount code or phrase on them so that they can get a discount at your business. It can be as simple as printing "Bring this card in for 10% off" on them. If you see a book at the library that's relevant to your business, slip your card in. If you happen to be looking at magazines, slip a few into relevant magazines. The key is to make sure it's inline with what the person is reading or looking at. For instance, if you own a business that sells crafting supplies, try slipping your cards into crafting books at the library. Alternatively, if you own a dog-grooming business, stick your cards in magazines about pets. If you mail out anything to your customers, be sure to slip in a card. For instance, include it in filled orders along with the product. That way, the customer has it on hand if they want to pass it along. Some people even go so far as to put business cards in everything they stick in the mail, including when they pay the bills.

Summary: Consider complementary businesses. Always have them on you. Talk to everybody. Ask at the Chamber of Commerce. Use community boards. Slip them in relevant places. Put them in mail-outs.

This is relevant if you have multiple fish in one tank. Isolating the sick fish will prevent him from transmitting disease to the healthy fish. To prevent possible ammonia and nitrate accumulation, do not put substrate or live plants in the treatment tank. Use a sponge filter in the treatment tank. It is less likely than a chemical filter to filter out medications, and is unlikely to stress your fish (like a strong power filter). Place an enclosed water heater in the tank to maintain a water temperature that is recommended for your specific type of fish. An air stone will help keep the tank well oxygenated. The supplies for your treatment tank are available at your local pet store. Continue to monitor the other fish for signs for fin rot. Separate and treat them if necessary. In the United States, over-the-counter antibiotics (e.g., erythromycin, trimethoprim, and sulfadimidine) are used to treat fin rot. The antibiotic is typically added directly to the tank's water. Carefully follow the medication's instructions to ensure effective treatment. Outside of the United States, you may have to obtain the antibiotics through your veterinarian. It is common to use a combination of antibiotics to treat fin rot, since the disease could be caused by several types of bacteria. Methylene blue is a non-antibiotic treatment that can also be used to treat fin rot. Depending on the severity of fin rot, fin rot can also be treated by trimming the affected fins to remove the damaged tissue. This medical procedure requires that your fish be sedated, so you will need to schedule an appointment with your veterinarian to have this done. Your veterinarian will use sterile scissors to remove the damaged tissue. He or she will then treat the clean edge with antiseptic. Your fish may need additional treatment if fin rot has become extensive. The fin tissue is more likely to grow back with minor cases of fin rot. Your fish should remain in the treatment tank until his clinical signs have improved. A good rule of thumb is to keep him isolated for about 10 days. During this time, look for improvement in clinical signs: normal color returning to his fins, healing of ulcers and lesions on his body, normal swimming behavior. Be mindful that the fin rot may be too severe for treatment. Effective treatment of fin rot involves both medical treatment and improvement of underlying conditions. Improving water quality is extremely important. Change the water to remove excess ammonia and nitrate from the tank and add fresh minerals to the tank. If need be, change the filter and allow time for bacteria to grow that will help reduce ammonia levels in the tank. Remove any dead plants to reduce ammonia accumulation. Reduce the stress in your fish's life by keeping him in his own tank, away from the other aggressive fish. You could also use a water heater and thermometer to keep his tank at the right temperature. Remove sharp objects from your fish's tank (e.g. gravel, sharp-edged decorations) to prevent further physical damage.
Summary: Move your sick fish to a separate tank. Administer antibiotic treatment to your fish. Trim the affected fins. Keep your fish isolated. Address the underlying conditions.
