Warm a small bowl of oil and massage it into your scalp. The oil will help moisturize your scalp and reduce flaking. If you want to use a natural oil, 5% tea tree oil has been shown to help in studies. Pure olive oil and pure peanut oil are sometimes recommended instead, but their use is controversial since they may provide food for dandruff-causing fungus. Rumors about the harmful effects of mineral oil, such as it containing toxins or clogs your pores, are probably unfounded, as long as you use pure mineral oil sold as a skin care product. Products that make claims to relieve dandruff are tested by the FDA and would not be allowed to be on the market if they were harmful or contained toxins. Gently warm the oil. Do not heat it too hot to handle, especially not to smoking temperatures. While this treatment may reduce dense dandruff faster than a single anti-dandruff shampoo application, it will be more effective if you leave the oil in for several hours. A shower cap may be handy to keep your hair clean during this time. Water alone will likely be ineffective at removing the oil. Instead, remove the oil with several applications of shampoo. If this is not enough to remove the oil, try leaving conditioner on your hair for 10 minutes, then rinsing out. A small amount of liquid dish soap can be used as a last resort, but it may damage or dry out your hair. A tar-based shampoo may also work, and will also help remove additional dandruff, but many people find this substance unpleasant due to its smell and ability to stain. Many oil treatments and long-term care shampoos can also be effective at reducing dandruff if left in for eight hours, typically overnight. Look for an anti-dandruff shampoo that contains both coal tar and keratolytics. If it does not advertise keratolytics, or substances which dissolve dead skin cells, look for urea, salicylic acid, or sulfur in the ingredients list. Find a well-fitting shower cap before you apply these, if you intend to sleep with them in your hair.

Problem: Article: Look for species that are categorized as non-aggressive. Tetras, Corys, and even some other types of Cichlids can coexist peacefully with Blue Rams. You will want to closely observe the interactions between various fish species to make sure that all parties are doing okay. Pay special attention to meal times as Blue Rams are leisurely eaters. Other aggressive eaters may consume all of the food, leaving only scraps for the Rams. This can cause starvation if not monitored and corrected. Male Blue Rams can become aggressive with one another if you don't carefully control population numbers. Try to keep a ratio of one male for every three females. And, remember to up the tank size if you increase the number of fish. German Blue Ram Cichlids are omnivores, meaning that they eat both meats and vegetables. Feed them twice a day, as much food as they can eat in two minutes. Flakes and pellets work well, as do frozen options such as brine shrimp. Supplement their diet with fresh veggies, such as small pieces of spinach or romaine lettuce. These can be dropped directly in the tank and the leftovers removed with a net, if needed. Be aware that some Blue Rams will not eat well after being transferred to a new environment. Try to encourage eating by offering delicacies such as mosquito larvae. If you want your Blue Rams to breed, it is best to start with a group of 6-8 juveniles of both sexes. Keep a close eye on the water conditions and provide lots of rocky terrain and let nature take its course. Be aware that your newly mated couples might lose a batch or two. This is nothing to worry about and they will eventually figure out how to successfully breed. They may also eat some the eggs from these initial batches. After you spot the eggs, you can either leave them in their current tank or remove them to a 10-gallon aquarium. If you remove them, make sure to wait 24-hours to ensure fertilization. Blue Rams are notoriously picky about water quality. Readings that would be acceptable for most freshwater fish can cause a Blue Ram to become ill. A water testing kit will contain everything that you need to monitor the water parameters. Blue Rams require a pH of between 5.5-7.5. Do not chase your PH; the general and carbonate hardness of your water is much more important. Rams do best with a general and carbonate hardness of 100 ppm or lower. If your hardness is correct, your PH will follow. Artificially changing PH is not the way to solve this. If your water is hard, you should mix your tap water with reverse osmosis water, or consider keeping different fish. Keep an eye on the readings of Ammonia, Nitrites, and Nitrates. Ammonia and Nitrites should be 0 at all times, while Nitrates should be kept under 20 ppm. Otherwise, a Blue Ram can essentially be poisoned by its own feces. To keep your tank up to Blue Ram standards, you need to do a 25% water change on a bi-daily or twice-weekly basis. Use this as an opportunity to clean your tank surfaces as well. You can suction out the debris from the rocks, etc. Blue Rams are generally quite healthy, but they can succumb to certain diseases and parasites. Ich is a parasite that can prey on Blue Rams. You will notice your fish acting listless if it is affected. Respond quickly with a tailored chemical treatment. Poorly bred Rams are notorious for suddenly getting emaciated and dying. If this happens with no other fish affected and ample water conditions, consider a different source of Rams.
Summary:
Find suitable tank mates. Feed them the right foods on the correct schedule. Make your tank suitable for breeding. Test the water regularly. Commit to frequent water changes. Respond to any concerns immediately.
