Aquarium Supplies Part 2 - My First Experience With Goldfish
by: Jonathan Wangsa


If you are seriously considering keeping fish as pets or are just starting out, I would like to stress again the importance of having some basic knowledge about aquariums and fish keeping in order to enjoy the hobby for a significant length of time and to avoid frustrations and disappointments.

In the first article I illustrated this by sharing my own childhood experience with bettas, and now I shall share my experience with goldfish.

While I still had my bettas I also wanted to keep some goldfish since I also found them attractive and interesting. My mom was reluctant to buy me some since I already had the bettas but she finally gave in and bought me a pair of "telescope" goldfish.

At the time I didn't have a real aquarium yet so we put the goldfish in a large jar (about 1 gallon). One of our neighbors told us that goldfish wouldn't tolerate chlorine and therefore, we should not use tap water. They happened to have a well and offered to let us use the water for my goldfish.

I soon noticed that the fish were constantly gasping for air at the surface. They also refused to eat. After a couple of days the water started to become cloudy, so I changed it totally. However, the fish still refused to eat and continued to gasp for air. Not long after that they became lethargic and eventually died.

My mom said probably "telescope" goldfish just weren't hardy enough and not easy to keep. However, I had not given up on goldfish yet, so I asked if I could try to keep other kinds and hopefully would have better luck. My parents eventually consented but my dad suggested that I get a real aquarium instead of putting the fish in a jar. You can imagine how elated I was that finally I was going to have a real aquarium.

So we went out and bought a 10 gallon aquarium and a few goldfish at the same time. I believe we bought 4 fish: a couple of medium sized "comets" and a pair of "pearl scales." We didn't buy them at a store, though. It was more like a wholesale type of place where there were plenty of different sellers selling their aquariums and fish. Again, at the time neither my mom nor I knew much about fish keeping. So we didn't buy any supplies for the aquarium. Just the tank and fish. That was it!

When we got home I filled up the aquarium with untreated tap water and immediately put the fish in. I was so excited to see the goldfish swim around in the tank, but that didn't last long. In a few hours the fish were no longer lively. They sort of stayed at the bottom and didn't move very much.

When my dad saw them he said they probably lacked oxygen and suggested that we go out and buy an air pump to aerate the tank. I had only seen aerated aquariums in places like public aquariums and fancy restaurants and thought that an air pump had to be very expensive, but my dad said it would be OK.

So my mom and I went to a fish store to look for an air pump. Besides the pump we also needed something to hook the plastic tube on to and hold it in place. We chose to get a frog ornament for that purpose (the air would come out of the frog's mouth). All the stuff didn't really cost too much.

As soon as we got home we hooked everything up and air started flowing into the aquarium. Like magic, within a couple of minutes the fish started to "wake up" and finally became lively again. My dad said, "I told you so!"

The air pump was about the only supply we bought for the aquarium. Having beautiful and lively goldfish in my very own aquarium was good enough for me. I loved them so much that I also fed them too much. I was happy to watch them eat. As you can imagine though, the water got dirty very quickly that I had to change it every day.

One day a friend of ours told us that we shouldn't be changing the water daily since it wouldn't be good for the fish. Also, in the mean time I had read somewhere that if you wanted to use tap water you should set it aside for a few days to get rid of the chlorine. Therefore, I set aside a bucket of water and changed 3/4 of the water about every 3 days.

I was able to enjoy the goldfish for a few months before one of them got sick and died and the others followed soon after. I was extremely sad and because of that my dad told me I couldn't buy any more fish. So, after all my fish died my hobby came to a sad end. Well, at least for a while.

Again, there is a take-home lesson here: if you're serious about having your own aquarium, there's some basic knowledge you need to possess before you even buy the aquarium and fish. You don't have to know everything there is to know about the hobby, but at least for the sake of the fish, you should understand a few things (such as how many fish you can have in a tank, how much to feed them, what kinds of aquarium supplies to have, and what kinds of maintenance you need to perform, just to name a few) that are crucial to their well being.

If you're an expert you most likely picked up on the things I did wrong in the story I shared above. If you're a beginner or just thinking about getting started with this hobby, I invite you to visit my web site (see below) to learn more.

REVOLUSI BIRU, UPAYA MENJADI NOMOR 1 DUNIA


Dalam rangka menjadikan Indonesia sebagai negara penghasil produk kelautan dan perikanan terbesar di dunia tahun 2015, Kementerian Kelautan dan Perikanan (KKP) menggagas Revolusi Biru sebagai grand strategy. Strategi besar ini diharapkan dapat peningkatan produksi, dan pendapatan nelayan serta pembudidaya ikan. Untuk itu, KKP menempatkan perikanan budidaya sebagai ujung tombak dalam memacu produksi perikanan nasional. Demikian disampaikan Menteri Kelautan dan Perikanan, Fadel Muhammad pada saat memberikan pembekalan kepada peserta Rapat Kerja Nasional (Rakornas) KKP di Balroom Gran Melia Hotel, Jakarta (17/2).

Revolusi Biru adalah revolusi mindset, suatu perubahan orientasi dalam melihat, menyikapi, economic opportunity yang sebelumnya dengan pendekatan darat (kontinental) menjadi pendekatan kelautan (samudera). Revolusi Biru yang dicanangkan KKP adalah: (1) memperkuat kelembagaan dan SDM secara terintegrasi, (2) mengelola sumberdaya kelauan dan perikanan secara berkelanjutan, (3) meningkatkan produktivitas dan daya saing berbasis pengetahuan, dan (4) memperluas akses pasar domestik dan internasional.

Pertemuan antara unsur KKP, Pemerintah Propinsi, Pemerintah dan Kabupaten/Kota merupakan bagian dalam meningkatkan produksi perikanan. Berbagai pertemuan tersebut telah menghasilkan komitmen gerakan bersama dalam peningkatan produksi perikanan, khususnya dalam upaya memacu produksi perikanan budidaya. Tahun 2009, produksi perikanan baru mencapai 10,065 juta ton, tapi tahun 2010 dan 2014 produksi perikanan ditargetkan sebesar 10,76 juta ton dan 22,39 juta ton. Produksi perikanan sebagian besar akan dipacu dari perikanan budidaya, yaitu sebesar 5,38 juta ton pada tahun 2010 dan 16,89 juta ton pada tahun 2014 atau meningkat sebesar 353%. Produksi perikanan akan ditransformasi, bila sebelumnya mengutamakan perikanan tangkap sebagai tulang punggung maka akan kedepan diarahkan ke perikanan budidaya dengan tetap berpegang penerapan Cara Budidaya Ikan Yang Baik (CBIB) atau Good Aquaculture Practices (GAP) sehingga memenuhi jaminan mutu dan keamanan hasil perikanan sesuai yang dipersyaratkan oleh pasar global. selengkapnya...

How to Select the Proper Pond Pump

Posted: 16 Feb 2010 08:18 AM PST


How to Select the Proper Pond Pump
by: Gerry Fung


Whether you have a preformed or a liner pond, a pond pump is a paramount component of any water feature. Stagnant bodies of water attract mosquito infestations, which are a nuisance, and also undesirable, due to the recent outbreaks of the West Nile virus. Therefore, it is paramount that you utilize a pond pump that circulates your body of water.

Pumps are available in both submersible and external (out-of-pond) models. For the smaller pond (up to 1000 gallons of water), a submersible pump is the more economical and practical option. Submersible pumps can be placed directly in the pond and require relatively little installation. They are free of distracting noise, and for smaller ponds, can easily be utilized to drain your pond (if you hook up a hose to the output flow).

In the old days, the main disadvantage of submersible pumps was that the pump seal could rupture and release oil coolant into the water. However, this is not the case nowadays, because newer pumps are magnetic-driven, and no longer require coolant. "Mag-driven" pumps are slightly more expensive, but they have the added advantage of consuming less electricity.

Pumps are sized by gallons per hour (GPH) output at one foot of lift or height. Manufacturers usually offer charts that break down the power of each size pump according to incremental heights of one foot. It is recommended that you circulate your body of water at least once every 2 hours. Therefore you will need to size your pump to ensure that it has half the GPH rating as the volume of your pond in gallons. For example, if you have a 1000 gallon water feature, you will require at least a 500 GPH pump.

Calculating the proper pump for waterfalls is a bit trickier, because you must estimate your waterfall's height. To do so, you must measure the vertical height from the top of your pump to the top of your waterfall. In addition, you must add another foot of height or lift for every 10 feet of hosing you will be using (this will allow for loss of volume from resistance within the hose). To calculate the required pump GPH, a general rule of thumb is that each inch of width of the channel will require an extra 100 GPH. For example, if your stream or waterfall spillway will be 10 inches wide, you will need a pump that produces an excess flow of 1000 GPH at your waterfall's height.

If you plan on having fish, your water circulation demands will be drastically increased. Fish rely on the oxygen in the water to survive, hence a proper pump for a fish pond must ensure that extra oxygen is both introduced into the pond, and distributed throughout the pond. The general rule of thumb is that you must double your pump GPH if you plan on raising fish. An example of a pump that would be appropriate for fish is GardenSuperMart's UltraFlo line of pumps. These pumps have oxygen intake valves and an unique air/water air mix system which effectively increases the oxygen concentration in your pond.

The advantage of GardenSuperMart's low-maintenance, magnetic-driven UltraFlo pump kits is that they contain a sealed unit with a large enclosure that prevents debris from clogging the water intake. The UltraFlo line of pumps starts at 200 GPH, and increase up to 660 GPH. All UltraFlo pump kits come complete with a telescopic riser and diverter and 3 fountain heads.

If you require a more powerful pump, GardenSuperMart also has a SuperFlo line of pump kits that can provide up to 1585 GPH. All SuperFlo kits come complete with a telescopic riser and diverter, 4 fountain heads, and a sponge pre-filter. An optional SuperFlo Mechancial and Biological filter can also be added to the pump to provide additional water filtration for your fish.

Both the SuperFlo and the UltraFlo pumps can be purchased online at GardenSuperMart's store, www.buypond.com. In late May 2005, GardenSuperMart will also introduce a new line of MaxFlo waterfall pumps that can provide up to 2780 GPH of pumping power. Please stay tuned for further news and details.

Betta Fish Is The Perfect Pet Fish

Posted: 16 Feb 2010 07:35 AM PST


Betta Fish Is The Perfect Pet Fish
by: Rosalinda Zamora


I still remember the first time I saw two beautiful looking fish in a friend's house. One fish was blue and the other was red, and they were swimming majestically in their fishbowls. That was my first encounter with a fish species known as Betta fish or Betta Splendens or Siamese Fighting Fish (three names that refer to one fish).

Up until today, I'm still keeping a few of them in my house, and they make perfect pet fish for my family. Every member of my family loves them.

Why do I like most about Betta fish, you may ask. Definitely, I have many different reasons, but here are three of them.

1. Betta fish are beautiful pet.

It's a tropical fish that comes with different colors such as red, blue and yellow. Some Betta fish have more than one color on their bodies. Believe it or not! I can spend hours looking at how Betta fish move in their bowls but even if you don't know a thing about Betta fish, you will be mesmerized by their colors alone.

2. Betta fish are easy to care.

Betta fish are hardy type of fish and they can live in a small container. A small fishbowl is enough to house one Betta fish, but be aware that two male Betta fish shouldn't be placed in one container. Or else, these two Betta fish might fight until death (that's why they are also called Siamese fighting fish).

3. Betta fish are responsive.

If you have a Betta fish in a small fishbowl and you move closer to the fish, you'll see that your fish will turn its head to look at you. That's what makes me fall in love with Betta fish. They are responsive to your presence and aware that you are there, unlike many other pet fish.

So, you can now consider if you want to adopt Betta fish as your family pet or for your kids. They are lovable creatures and you will know it immediately one you have a Betta in your house.
