A healthy aquarium isn't terribly hard to maintain, but careful preparation must go into getting it up and running properly!  .

Aquariums house beautiful animals and plants, are entertaining and proven stress relievers, and can be educational, too! As with caring for any living being, aquatic pets require regular attention for their welfare, and to a beginner, the process may seem overly complicated. But in truth, the opposite is true: aquatic pets are among the easiest to care for, and may be surprisingly inexpensive. Once you have your aquarium properly up and running, it is primarily a matter of regular observation and maintenance.

If you want an aquarium in your home – great! It can be an incredibly rewarding experience. Just make sure you enter into this hobby prepared to spend some time choosing the type of fish and designing a system to help them thrive while reducing your maintenance load.

Why Keep Ornamental Fish?

The keeping of ornamental fish (a generic term referring to aquatic pets that includes fish, invertebrates, corals, and live rock) is of great interest, joy and comfort to a large segment of the world population. The connection with nature inside the home is one of the easiest ways to help children get more in touch with the world around them. On top of that, Ornamental fish have been shown to provide health benefits, including helping people suffering from dementia and alzheimer's:

Fish keeping also improves the world we live in as captive bred species of fish and corals have helped reduce that which is taken from the wild as well as helping to replenish depleted supplies, including some that are or were threatened. In some African and South American regions, the harvesting of fish improves the environmental conditions by eliminating what would be large die offs that would otherwise have huge negative implications for the aquatic environment. Harvesting also acts as a revenue source to maintain native residents (see project Piaba as an example). Additionally, live fish are used in many research projects that have led to health improving medical advancements which provide a greater good for the world population. Lastly, keeping fish helps all of us understand the interconnection between fish and planetary ecosystem health.

Before You Get Started

So you want an aquarium? Three things to consider before you get started are:

  1. What do I need?  In addition to the aquarium itself (tank, filter, lighting, heater, thermometer) you may also need to factor in the accessories and decorations: a net, test kits, plants (plastic or live) and substrate! And did you remember your dedicated bucket, dechlorinator, water conditioner to make the environment safe for your fish, and siphon? And don't forget the most important part – the animals themselves!
     
  2. Do you have the time? A fascination with marine animals or Malawian cichlids are great intentions, but you also have to have the time to spend each week for regular maintenance to keep the environment in top form for your aquatic pets. You have to realistically assess your lifestyle and your ability to handle the minor daily and weekly items an aquarium requires. The good news is that once an aquarium is set up properly and running, it won’t take much of your time at all. Daily, you will need to check out the fish for any visible health issues that might be underway, check your water to be sure the temperature is in range and feed them (smaller portions more often during the day is best). Weekly, you will need to monitor the water quality and should do a small water change (10-15% of the tank water).  Monthly, some minor cleaning and you’re all set. All total these tasks typically take less than an hour or so of time depending on the tank size. Remember, the fish are live animals and interacting with them each day is important to their wellbeing. If you keep highly irregular hours or travel a lot, and are the only one in your home who can (or will) reliably take care of your aquarium, it may not be a hobby you should undertake at this time.
     
  3. Do I have enough or the proper space to set my fish tank up? What good is a deluxe, 300 gallon aquarium if you have nowhere to keep it? Before you pick out an aquarium, make sure you have a comfortable place in your home near a power outlet, a source of water and preferably a drain or somewhere you can get water from the tank to outside plants using a siphon hose. You want to be sure the tank will be away from high heat areas, direct sunlight, heavy foot traffic, or radiators and vents that can cause rapid temperature change.

Getting Started

If you know you will have the time, space, and budget for an aquarium, it's time to lay the groundwork for your new hobby!

First, make a list of the fish and other aquatic animals you are interested in, then research them for size, behavior, and water preference. Researching should winnow your list down significantly, removing from consideration fish that will grow too large for your aquarium, attack tank mates, or require special Ph, salinity, or temperature that significantly varies from most of the other critters on your list.

Once your list is complete, figure out your budget and select your aquarium and accessories. Smaller tanks are less expensive to purchase and maintain unless they are so small that they require additional equipment to keep the fish healthy or are too close to the fragile edge that you will always be fighting water quality issues. Another important consideration is that they take up less space, which can make them more suitable for somebody who lives in an apartment or small home.

Larger tanks are more expensive to purchase, but often times require less regular maintenance due to water volume. Of course, they are able to comfortably house more animals, and are less prone to sudden shifts in temperature and water quality. While the final choice is your own, many experts recommend that you get the largest tank that you can afford and fit in your home. The simple reason for this is that many hobbyists become so enthralled with their new aquarium, they quickly wish it were larger!

Now that You Have Your Aquarium -- Hurry up and Wait!

It will likely take an hour or two to set up your aquarium, fill it with gravel, plants, and water (did you remember to treat the water to remove harmful chlorine, chloramine or heavy metals in it?), and get that rewarding feeling once you are done -- but don't jump the gun by putting any animals in it just yet!

Step back and pat yourself on the back for a job well done, and keep an eye on the tank for at least the next day to make sure everything is in proper working order.

Once you are sure there are no leaks or malfunctions (after 24 hours of running time), pick out some of the smaller, heartiest, common fish off the list you made earlier (zebra danios or goldfish are great examples). The size and number of fish is important – at this stage try to limit the number you choose to about one inch of fish per every 10 gallons of water in your tank.

Introduce these fish to your aquarium, and once again: wait. You are going to want your aquarium to cycle, which can take up to 8 weeks. You can speed this process along by using a tank starter which is beneficial bacteria in a bottle or by using a seeded cartridge for your filter or foam bubbler from your local fish store. During this time, watch your tank like a hawk -- change out small amounts of water regularly, be absolutely sure not to overfeed (of course, this is always important even though your fish will always look hungry when you pass by the aquarium), and check ammonia and nitrite levels. You are waiting for bacteria to grow that will naturally break down the ammonia that fish produce through digestion -- as toxic as ammonia is for fish, the bacteria love it, and by eating it, the bacteria actually help keep the aquarium habitable.

Add new fish to your aquarium slowly -- and avoid adding more than the tank can handle.

Once your ammonia has increased (spiked) and then dropped to almost zero and your nitrite levels have dropped to zero, within 8 weeks typically, you can begin slowly adding more fish and aquatic animals to your aquatic environment, until your "fish list" is complete. This is provided of course that your local fish store agrees that the number and size of fish you have chosen match your aquatic environment. Slow is the most important word here -- adding too many fish at once will stress the tank, and could even force you to cycle it again.

Maintain and Enjoy

With a fully functional and populated aquarium, it should be fairly easy to maintain a safe and clean environment simply by observing and conducting the minor maintenance tasks noted above. When feeding make sure you are feeding only the amount of food your fish can completely consume within about 30-45 secconds. Always, keep a watchful eye on the health and behavior of your animals in order to stay a step ahead of any trouble that may come along. The "an ounce of prevention is worth a pound of cure" saying is especially apt in a tiny ecosystem like an aquarium! From here, keeping fish can be a daily connection with nature and a rewarding hobby that gives more back to you than you give for years to come!
