How to Care for Aggressive Aquarium Fish

Raising fighting fish might seem like an attractive idea, but are you capable of raising healthy, happy fish in your home? Here are tips to help you do that.

Types and Number of Fish

Some fish can be territorial or shoaling types, while some fish are labeled semi-aggressive, because they are sensitive to unsuitable tank conditions. This is precisely why you need to research about the different species first before purchasing anything.

Some fish can get along with others of the same species, while there are some that should be kept alone in a tank like the green-spotted puffer, oscar, and betta fish. Others, however, become aggressive if they are not kept in large enough schools. Each species need different requirements especially when they’re still growing. Always stick to the rule of once inch of fish per one gallon and anticipate how large the fish will get so you can already set up the right aquarium.

Aquarium Setup

Aquarium hobbyists will tell you that you should get the largest possible aquarium you can afford, because larger aquariums make water conditions easier to control and it will give more room for your fish. Research about the fish’s natural habitat, because this will also help you determine how best to setup its tank.

Each fish has different water condition requirements, such as temperature, salinity (if it’s a saltwater fish), pH level, and others. Territorial fish also need barriers such as plants, wood, rocks, caves, and other tank ornaments. Even the lighting can provide barriers for the fish, as long as you know the lighting and temperature needs of the species.

Diet and Health

Feeding can be tricky especially if you keep species with different feeding habits. This could trigger aggression among your pets when they try to race for the food. The best solution is to feed them in different places in the tank with small amounts of food. Take note of their feeding habits based on the lighting and time of the day as well, because some prefer to feed in the dark and come out only after sunset.

While feeding, you should also observe the fish for signs of problems such as injuries, loss of appetite, rapid gill movements, and lethargy. Unusual behavior could signal bad aquarium conditions or diseases.

Fish Behavior

Behavior that will seem problematic might also turn out to be normal for some species, such as rearranging decorations in your tank, refusal to eat if the diet isn’t varied, swimming near the surface, and swimming quickly around the aquarium. However, these can also be indications that the fish is stressed and that you need to check your tank condition.

If you’re keeping a community of male fish, you should also expect some fights. These can be reduced if you limit the number of each species in the tank and there is enough space and barriers to break their line of sight. Remember that overcrowding can be a problem for semi-aggressive and aggressive fish.

Hair Care Myths and Facts

You will find hundreds of hair care beauty tips on the Internet, but how do you sort the facts from the myths. This list provides you with the most common hair care myths that you should stop believing.

  • Washing your hair daily will not make it dull and dry. If you have dry hair, it’s most likely from applying a lot of chemicals, exposure from heat, and over-styling.
  • Shampooing twice is good for the hair. Well, not really. Wash your hair once daily to keep it clean but doing it more than once can strip it of its natural oils.
  • Exposing your color-treated hair to heat and bleach will change its color. You might want to stay away from the beach, spa, and pools in Singapore during hot days if you want your hair to stay healthy and shiny. If you need to go out, make sure that you apply a sun protector on your hair or wear a hat.
  • It is better to wash and rinse your hair with cold water. Hot showers are divine, but you should opt for cold baths if you love styling your hair. Just like heat and chemicals can damage your hair, so will hot water.
  • Hair doesn’t grow faster if you trim it regularly. Remember that your hair does not have blood vessels, so it would not know the difference if it has been cut or not.
  • Regular brushing does not necessarily make your hair shiny, but brushing is a good way to massage the scalp and bring out the natural oils that protect the hair.
  • Rubbing your hair vigorously with the towel will not necessarily damage it, unless of course you already have damaged hair from too many treatments and hair coloring. Remember, however, that the water in your hair can potentially reduce its tensile strength when friction is applied.
  • There is no remedy for split ends, so save your money instead of buying hair repair products. Regular trimming will make your hair look less damaged, but it will not solve the problem either.
  • Extreme stress can cause hair fall, but alopecia is rare unless you have a genetic predisposition to baldness or your hair is extremely damaged.
  • Pulling out one strand of hair does not mean two strands will grow in its place. Ingrown hair comes from improperly shaving or pulling hair.
  • Coloring your hair while you’re pregnant can have negative side effects on the child, however, the studies are conflicting. Still, most stylists and doctors will advise against it.
  • You do not need to change your shampoo and conditioner regularly if they already work. Your hair does not magically develop an immunity from the chemicals. However, if you have chemically-treated hair, you should switch to sulfate-free shampoo and conditioner to avoid damage.
  • Coloring can cause hair damage. To some extent, yes, it can weaken your hair. But if you want good results, consult a reputable stylist and use only the best products you can afford.

A Better Understanding of the Strength of Men

When it comes to being a man, there’s usually one attribute which people think of and this attribute is none other than something we like to call, strength. That’s just it. Everybody expects a man to be strong. You know what the worst part is? Well, everybody expects a man to be strong physically. This isn’t always the case guys.

We’re Not Talking About Muscles

Men aren’t measured by how physically strong they are, men should be measured by how emotionally and intellectually strong they are. Not every buy is into physical fitness, let’s face it. Some guys prefer other things. But this does not definitely make them less of a person, no. This in fact makes them unique.

The moment they embrace their masculinity in their own way, they become better than those who seek masculinity through their physical appearance. You know what really makes a man strong? His confidence. That is the biggest strength anyone can have. Okay, not everybody was born equal, some people are better at some things while others have a hard time on those specific things.

Each Man Excel Differently

Some people excel in other places while others excel in the good old-fashioned things. This has nothing to do with confidence is built when you are not comparing yourself to other people. Other people can be good at whatever they want but you? You should focus on what you want and not how society expects you to perform. The thing about society is that everybody speaks within a certain norm.

A huge chunk of society just wants to be better than other people. A lot of them are capable, yes, but not a lot of them are strong. A lot of them haven’t even fully accepted who they are both through their strengths and weaknesses. The hardest part of being confident is admitting you made mistakes.

Struggling on in the Face of Challenges

Once you’ve made mistakes, it’s time to man up and face them. Nobody is perfect and nobody has it on their side every time. Some people have worse but that’s not the point. People go through ups and downs in their life and the only way to face it is with confidence.

You don’t need to be the best at everything, you just need to accept who you are and be the best at being you. The physical aspect of strength should only be a source of fitness and not a measurement of masculinity. Although it’s great to look good, looking good isn’t the most important thing in the world. The most important thing in the world is to be happy with who you are.

Atari Games for the Nostalgic Gamer

Atari may no longer be a major player in the video game industry, but its contributions in gaming is undeniable. Not all of us were born during the years Atari was still active, but there are titles that you can still play today if you know where to find them.

Why is Blood Typing Important?

Blood typing is important in the hazardous blood transfusion procedure, but what are the blood types and how are these determined?

Blood Types and Genes

Your blood type is determined by your genes, specifically by the combination of the alleles you inherit from your parents. If you can recall from your biology class, alleles are the forms of the gene within one chromosome which are responsible for the codes of enzymes that create the A and B antigen. Possible combinations include, A, AB, B, and O which make up the ABO blood group. You might be surprised, however, that there are at least 20 blood group systems today including the Rh (rhesus) factor blood group, which is characterized by the presence of Rh antigen in the blood. This then makes up a total of 8 blood groups in humans.

Mixing Blood Types

How did people know that using a different blood type on a patient is fatal? You guessed it. Failed experiments in blood transfusion that resulted in deaths happened until 1901 when the human blood groups were finally identified by Karl Landsteiner. Mixing two different blood types will result to agglutination or clumping, causing cracks in the red cells, releasing toxic hemoglobin. The response is triggered by the body’s immune system which produces antibodies against the foreign blood cells. As a result, the blood vessels will clog up and stop circulating.

Finding Your Blood Type

To find out a person’s blood type, a blood sample must be taken to a laboratory and mixed with three reagents of three antibodies for A, B, and Rh. The laboratory technician will then observe what will happen with the mixtures to determine which one has agglutinated and are not compatible for the person’s blood type. The sample that shows no indication of agglutination is considered compatible. People with Rh negative blood can receive donated blood from Rh positive donors, but the next time he/she receives another set of Rh positive blood transfusions, there could be a problem.

Compatibility Issues

Even between a pregnant woman and her fetus, there could be some problems in the blood compatibility, if for example, a father is Rh positive type and a mother is an Rh-negative blood type. Their combination will result in a fetus with a positive Rh antigen. The result could be fatal for the baby and may result in hemolytic disease caused by the mother’s antibodies attacking the fetus’ red blood cells. Thankfully, this can be prevented with injections of Rh immune globulin during pregnancy and after delivery of the newborn.

Blood, Tissue, Organ, and Marrow Donation

Blood transfusion might be recommended in the following cases: severe anemia, bleeding during surgery, injuries and blood loss, cancer, and bleeding disorders, but careful testing is always done. Even when receiving tissue, organ, and bone marrow from a donor, both the recipient and the donor should be tested for compatibility before transplantation. Blood typing and HLA testing are done to ensure that the donor and the recipient match.

Four Easy Ways to Help You Improve Your Posture

Having great posture goes a longer way than simply staving off a slouch and making you look tired or unconfident: great posture is also about keeping your body, and more importantly, your spine, aligned correctly in order to minimize strain. With proper posture, you will not only experience far lesser pain in your neck, shoulders, and back, but you also help strengthen otherwise weaker muscles, and even improve your overall breathing.

Here are five easy ways that will help you improve your posture:


Maintain a straight back when carrying a load. Ideally, you should be lifting items with your core engaged and your heat upright while your knees are bent and taking most of the weight. As you lift the object towards you, position your shoulders and bend only at the hips and knees.


Maintaining proper posture when sleeping is just as important when you’re awake. Whether you’re lying flat on your back or on your sides, keeping your spine straight is a great way to reduce back pain and guarantee more, and better, sleep. To do this, be sure to maintain your spine’s natural posture by keeping only one pillow and let your head rest on it, rather than your shoulders on your neck.


Slouching when you’re standing not only gives other people the impression that you’re unconfident, but also add more stress to both your feet and your spine. To avoid this, it’s important to keep in mind that standing properly involves positioning your pelvis and your spine to take that stress, rather than the spine and the feet. Aside from wearing flat shoes for better support, be sure to follow these steps in order to stand upright properly:

  • Keep your head upright and center (chin must be parallel to ground)
  • Pull back your shoulders gently
  • Draw in your stomach slightly
  • Unlock your knees
  • Keep your feet shoulder-width
  • Center your weight on your feet

Aside from appearing more confident, which is a definite plus wherever you go, standing straight also gives you the boost of energy that you need to get through the day.


When you’re facing a computer screen all day, it can be difficult to maintain proper posture when it’s much easier to simply slouch. However, this has the cost of straining your back muscles and ligaments, as well as adding unnecessary pressure to your spine.

Aside from choosing the right chair that accommodates your height, it’s also important to keep your arms bent to ninety degrees and allow your back to rest on the chair’s lumbar support, which you can do by standing straight.

Additionally, be sure to prevent unneeded neck strain by making sure your computer screen is within eye level.

Five Crucial Ways to Keep Your Blood Pressure in Check

Unlike other types of health conditions, having a high blood pressure isn’t always something you can see or feel, and you don’t usually know you have it until it’s serious enough to cause significant problems and increase your chances of getting other complications.

However, the good news is that you don’t always need medication in order to improve the symptoms of hypertension. In fact, there are many lifestyle changes you can adopt in order to keep your blood pressure in check, such as the following:  

Decrease your salt intake

Sodium is the easiest way to raise your blood pressure, and if you notice that your heart rate is up after eating a hearty meal, then you need to change your dieting habits. While you can’t eliminate all sources of sodium from your diet (you still need to consume a small amount for your body’s daily needs), you can shift towards a cleaner and healthier diet with more fruits, vegetables, and whole grains.

Watch your waistline

The bigger the number on the weighing scale, the higher the blood pressure also tends to be – but that’s not the only thing you need to be looking out for. Aside from a high blood pressure, having a high body mass index in proportion to your height can lead to conditions such as sleep apnea, which can also further raise your blood pressure. Losing a small amount of weight can be really helpful here, as well as keeping an eye on your waistline.

Take deep breaths

When you have high blood pressure, means that your system is compensating for not having enough oxygen by trying to get it as quickly to your entire body as possible, and this is where deep breathing comes in. The best way to inhale is by imaging your stomach as something like a balloon. Take a deep breath slowly and allow that balloon to inflate, and exhale slowly.

Sleep early, wake up early

Not getting enough sleep is another big factor that contributes to stress, which in turn contributes to higher blood pressure. To make sure you get enough sleep, you can try setting your alarm to make sure you go to bed early at night and early in the morning for a full seven to eight hours of sleep.

Learn effective stress management

The most important thing you need to know when you have high blood pressure is that you not only need to minimize getting into stressful situations, but that you also need to know how to handle them better if you do encounter them.

This includes, but isn’t limited to, balancing work and life in a way that lets you get the most out of both. If you think you’re focusing on work too much, it’s best to allow yourself to take a break to focus on your loved ones and your health.
