Keeping Aquarium Sharks


Who’s afraid of sharks or would it be nicer if I’ll ask who wants to keep sharks?

Sharks are known to be very dangerous to humans and most of all to other aquatic animals. But a lot of people have seen how beautiful sharks are. Some fish enthusiasts even keep them inside a fish tank. Pretty cool yet you need to be careful with your choice of tanks as well as the water condition for such kind of fish. When you plan to house a shark in your home, you need to know many things to be able to successfully keep them well.

If this is your first time in fish keeping hobby, a shark isn’t the right kind of fish for you to keep. This isn’t the time yet to keep a shark, you need to have the quality traits of a good fish keeper in order for you to keep this kind of fish. Even those that are in this hobby for a long time didn’t possess yet the qualities of a good fish keeper, neither them can keep shark in their tank too.

For those who believe they are capable of keeping this fish, then go for it but be careful. Just buy one or two sharks. Most of the sharks are aggressively stronger than other fish and even to their own kind, which usually creates a high risk of stress inside a fish tank. For larger fish tanks, especially those that are for public views, you can find a number of sharks inside the tank. Some of the sharks tend to befriend its kind but only very few of them get along together.

Become aware of your shark’s behavior and where it comes from. Study its physical features if you can see any symptoms of stress or poor health – any lost scales, does it have any cuts from its body, visible spots and blemishes, check the fins if it’s held close to the body. Verify the fish tanks of the pet store where you brought your shark- are they tidy and well kept? Is your source person of the shark knows well about the subject and a shark enthusiast? It is good to have a reliable person to talk with regarding sharks because if you have any concerns you can address that to the right person and be able to get the right answers.

You should ask how they caught the shark. Why do you need to know that? This is because you will through this you will know if the people behind this activity are good, if they caught the shark in a proper way, not illegal, not harming other sharks in the natural environment. If you happen to meet other shark enthusiasts or even those who are fish lovers who shares the same passion you’ll be able to share this hobby to others by convincing to keep one as a way of supporting a campaign about stopping the shark finning, it is by pulling out shark population in the wild. By owning one shark and keeping it safe is a way of supporting the campaign for pro-aquatic life.

In order for your shark to be safe you need to house it in an appropriate tank and environment. Are you confident that your fish tank can withstand the aggressive behavior of shark? Is it big enough to offer a great venue for the shark to swim around and show its natural behavior? Does it have any covers preventing the sharks to jump out of the tank? Are the lights of your tank following the natural day and night rhythms in the natural environment of the shark? Do you have any rocks, caves or plants as ornaments in your fish tank, where sharks could hide whenever they want to?

Set up a good filtration system in your fish tank. Utilize a good electrical filter to maintain the cleanliness of your tank, take into account biological filtration too! This type of filter is guaranteed to have a greater amount of good bacteria than bad bacteria which are sometimes toxic in the fish tank, maintaining the whole tank to be healthy and clean for its inhabitants. By having a thin layer of substrate or gravel at the bottom of the fish tank helps the filtration by giving a good area for beneficial bacteria can thrive.

It is essential to keep a good water quality of the fish tank, constantly check your water to be sure. The best way to keep your aquarium healthy is to check it regularly. Maintenance includes replacing 15-20% of the water every week, scraping of algae on the tank’s walls, removing dead fish if there’s any, checking all the aquarium devices if they are still functioning well, testing the quality of the water. If you’re too busy to do all the regular maintenance of a shark tank, forget about getting a shark.

Maintain a water temperature suitable for sharks; don’t go less or over its optimum range. Place your shark tank away from which the sunlight loves to show its light. As mentioned earlier the water temperature should stay at the optimum range for sharks because if it goes beyond the most favorable range or if it did not reach the optimum range it will cause stress to sharks making them more sensitive to becoming sick. Like any other fish, don’t overfeed your shark. Drop a variety of foods but be careful, only recommended foods should be fed to sharks and again do not feed with large amounts of foods. Overfeeding will just give you too much to work on, either the shark gives off too many wastes or the uneaten food will decompose in the water creating a poor water quality for your shark.

Check your shark in regular basis to see any signs of illness. Indications of illness show that the shark’s surrounding is not in good condition thus making its inhabitants sick. Continue to be watchful in terms of your shark’s physical features and behavior that could tell you any signs of stress or any health problem. In most cases the root of any disease or sickness in fish such as parasites or infections is by having a poor quality of water and taking for granted the poor tank condition. Prepare a separate tank that will serve as a quarantine tank to house a sick fish for treatment or if you see any signs of health problems with your shark can put it in the quarantine tank until you’ll figure out what’s wrong with it. In this way you will be able to stop the spread of disease in the whole tank and lets you focus your attention to the one that’s really need the treatment, not the entire tank.

Enjoy your sharks and share it to others the breathtaking experience of such kind of pet!

Aquarium Decors: Think Twice!


Setting up an aquarium could sometimes be very tiring but enjoyable as well. If you want to have a beautiful aquarium for your fish to live in, you can put decors in it. Finding the right decors for your fish tank is both hard and easy. Hard because you need to check the decors if they contain harmful chemicals that are toxic for your fish, on the other it can be easy because you can just ask around the right decors for your fish tank.

You can find a lot of fish tank decors and colorful unique materials that are great for beautifying your fish tank, they can brighten up your dull aquarium and the list of these ornaments will go on and on, but the important part here is to choose the ornaments that best fit your fish tank and fish as well.  Plastic materials and rocks like limestone are not recommended for use because they will soon degrade and will eventually alter the water chemistry consequently causing hazards to fish.

Some materials used in manufacturing aquarium ornaments contain limestone which are easily dissolved in water and that will increase the hardness of the water and raises the pH level too, thus making the water more dangerous. Almost all aquarium fish won’t be able to withstand this kind of water leading them to die fast. Cockshells and corals are also avoided for the same reason, since both materials will increase the degradation of water. Forget about how they look, surely they’re lovely but think over the damage they will cause if you put them on tank.

There are many ways how to know if a material contains limestone. Here’s how to do it, take a small piece of that ornament on a flat non-absorbing area and put some diluted acid or vinegar on the surface of the material. If you see small bubbles surfacing in that piece of material then it’s clear it contains a limestone, therefore it needs to be avoided.

There are a lot of great options of aquarium ornaments available in many pet stores. For instance Granite, it’s a great substrate, natural rocks on the other hand can also be taken into account. One of the most common aquarium ornament is an aquarium plant but you need to be ready for the maintenance since it requires additional time and cost.

Lastly, if you would like to add any decors in your fish tank it’s vital to wash them properly with lukewarm water. It is recommended to soak them at least 2 to 3 days to get rid of those harmful materials like any metal chips.

Liquid Fish Food


A type of fish food that is becoming increasingly more popular, especially among fish breeders, is liquid fish food. Having food for fish available in a liquid form can make some of the components of the food more bio-available to fish, and may also have some other health benefits for good pet care. However, the majority of fish owners are unaware of the benefits of liquid fish food, which can promote good health in overall pet fish care. There are several different type of liquid fish food formulas available on the market today, which may or may not be the best fit for your fish’s nutritional needs. Here is some general information about liquid fish food formulas.

 

LIQUID FOOD FOR BABY FISH

The use of liquid fish food formulas is sometimes used to feed baby fish, or ‘fry’ as they are sometimes called. Liquid fish food formulas provide an aqueous suspension of tiny food particles, which are much easier for newly hatched fish to ingest. Because baby fish grow at such a rapid rate, they will thrive off of a diet that provides them with a constant supply of nutrition.

INGREDIENTS OF LIQUID FISH FOOD

Some of the most common ingredients in liquid fish food formulas include:

CALANOID COPEPODS

Calanoid copepods are a type of zooplankton that is in the order of copepods. There are approximately 2000 different species of calanoid copepods, which may reside either in saltwater or freshwater environments. The reason why calanoid copepods are a valuable source of nutrition for fish, is because they ingest phytoplankton and algae. This ingested food is then converted by the calanoid copepod into a more digestible form, which provides better nutrition for other animals, such as fish. Most commercially grown fish are dependent on calanoid copepods for a source of nutrition, which may be consumed either in their adult or larval forms. In most cases, calanoid copepods are freeze-dried before they are added to liquid fish food formulas.

NANNOCHLOROPSIS

Technically, nannochloropsis is a genus of alga that was first classified in 1981. For the most part, nannochloropsis is spherical in shape, and lacks chlorophyll b and c (unlike other related microalgae). However, nannochloropsis contains a high level of polyunsaturated fatty acids, which are often used for many different industrial applications. As an additive to liquid fish food, nannochloropsis provides a high-energy food source for most pet fish.

TETRASELMIS

Tetraselmis is a type of phytoplankton that is commonly used as a nutrient source in liquid fish food formulas. By description (in its natural state) tetraselmis is motile, green and very tiny. Tetraselmis is valued for its extremely high level in natural EPA lipids. In addition to this, tetraselmis also contains a fairly high protein content. Tetraselmis is also able to stimulate feeding in many different types of pet fish, by using its natural amino acids. In its digestible form, tetraselmis contains a 54.66% concentration of protein, a 18.31% concentration of natural carbohydrates and a 14.27% concentration of total lipids.

A Jawfish and Cat Tale


by: Bill Winterholer

One story I would like to share is that of my cat Oreo and his Yellow Headed Jawfish friend.

I have had several fish since I started my marine interest, Damsels, Seahorses, Shrimps, etc., but of all the fish I have had, and unfortunately have lost, the one that always sparks Oreo’s interest is the Yellow Headed Jawfish. Any other fish in the tank gains only a passing interest for Oreo, but put a jawfish in the tank and that darn cat suddenly is absorbed in it. He would hang off the hood of the tank peering for a glimpse of the creature. I finally ended up putting a chair in front of the tank just for him, and I am not joking when I say that he would sit there for hours watching this fish.

Sadly the first Jawfish we had jumped to his death from the tank one night and Oreo whined for days, as if grieving for the loss of his fish friend. We obtained a second jawfish months later and once again Oreo was mesmerized. Oreo was in joy to have the fish back, and again the chair was placed in front of the tank.

Unfortunately, this fish followed the same fate as the first, and again Oreo was at a loss. I haven’t bothered to buy another Jawfish until I can figure a way to prevent the fish from jumping out of the tank, but I can imagine Oreo will love it when we do.

Precious the Cat Takes a Dive


by:  Bill Winterholer

I became interested in raising fish not long after I moved into the home we’re in now and began a garden pond. In my pond I had goldfish, and became interested in the many species of goldfish. During the winter I began to keep Orandas in a 29 gallon tank in my basement. There were two redcaps in the tank.

I had a Whisper filter attached to the end of the tank and covered it with a piece of plexiglass. This glass was 1/4 inch thick and covered the whole tank, except for about two inches at one end where the filter was hung. Unfortunately, my cat Precious liked to perch upon the plexiglass and stab her paws at the fish as they passed by. I was constantly chasing her off of the tank, as I was fearful she would kill the fish.

One evening, perplexed after having chased her off for the third time, I finally removed the plexiglass and in its place stretched out a sheet of Saran wrap. My wife knowingly grabbed a bunch of towels from the hamper in the bathroom and we sat down – my wife to watch a TV show, and I to do my usual computer chores.

Not more than twenty minutes later I was distracted by the sound of a SPLASH, then the howl of a very, VERY angry cat hauling her soaked self out of a fish tank. Water was EVERYWHERE, and when we tried to approach her, towels in hand to dry her off, she bared fangs and unsheathed claws. She knew what we had done to her and wasn’t liking it, but Precious never dared perch herself on the tank again!

Hope this brings a smile to your face.

A Small Fish Story


An Irish Folk Tale

Retold by Louise Carus from The Real St. Nicholas: Tales of Generosity and Hope from Around the World

We’ve hunted high and low and haunted libraries—including the greatest folklore library in North America at Indiana University in Bloomington—to find more stories about St. Nicholas from the British Isles. This is the only story we’ve been able to locate. —LC
While St. Nicholas was generous to others, he did not lead a grand life himself. He was even once a beggar who traveled all over the country with only the clothes on his back, his staff, and an old wooden pail. One day, he came to a little town by the sea where almost no one was willing to help him. All day he stood on the street, asking for alms. But by the time evening fell, only three people had taken pity on him: a fisherman, a woman, and a priest. Strangely enough, each of them had given him the same thing—not a coin, but a small fish.

He put all three fish in his pail filled with water and walked on until he came to a house where a very poor widow lived with her children.

“Begging your pardon, madam, but might a person stay here overnight?”

“To be sure,” the widow answered wearily, “but we only have water soup and a crust of bread for supper.”

“Supper won’t be a problem! Look here: I have three fish. You can fry them and we and the children will all eat them together.”

The widow looked doubtfully into the beggar’s pail. She had no way of knowing the three little fish had been growing in there. By the time she saw them, they had become quite large.

“What a joy,” the woman cried. I haven’t seen such big fish for a long time, not even at the market!”

One fish, two fish, three fish do I see,
Plenty for my children and enough for me!

She happily lit a fire and began to cook the fish over the glowing coals.

While she was about her work, the Saint asked, “Do you have a pail?”

“Yes, indeed I do.”

“I’ll thank you to fill it with water and bring it to me.” The woman did as he asked. Soon the fish were ready to eat. And how delicious they were! The widow and her children were so hungry they left nothing but the bones, Nicholas said, “Don’t throw those bones away. Give them to me.”

The children and their mother looked at one another in surprise. “What is he up to?” they whispered. But they were so grateful for a good meal at last that they didn’t question Nicholas.

After they had eaten, the family lay the bones of all three fish on a plate. Nicholas picked up the bones by the tail and threw them into the widow’s pail.

Again everyone was surprised. “Why is he doing that?” they wondered.

Then as the widow was about to carry the pail outside to empty it, she noticed three live fish swimming in the water! “What?” she gasped. “How could that be?”

One fish, two fish, three fish do I see,
Plenty for my children and enough for me!

Who knew where the fish came from but Nicholas, and by that time he was sound asleep.

The next morning, the good Saint said, “Please fix these fish for breakfast.”

The woman gladly did so, and once again everyone had enough to eat.

When they were finished, again Nicholas said, “Bring me the pail and give me the bones.” Then he threw them into the water and continued, “You must always do this. That way, you will always have fish and you and your children won’t be hungry any more.”

Then the Saint swung his wooden pail over the end of his staff, said goodbye, and walked off down the road.

The widow and her children never saw St. Nicholas again, but they lived well for a long time. At last, one day the mother left a single child alone at home while she and the others went to visit relatives. The child at home got hungry, so he tiptoed over to the widow’s pail and looked in:

One fish, two fish, three fish do I see,
Enough for the others and plenty for me!

With that, he scooped out one of the fish and fried it for himself. Afraid that his mother would find out and scold him, he threw the bones away.

When the widow returned, the first thing she did was go to the pail to prepare dinner.

One fish, two fish, thr——

But now there were not three fish swimming in the water—there were only two. And from then on, that had to be plenty enough for all of them!
