How does one set up an aquarium? Here are some necessary principles.
- Choose a rectangular-shaped tank made of glass with metal frame over bowl-shaped one.
- Cover floor to about two inches with coarse sand and gravel (about 1/8 inch in diameter) to serve as anchor for plants. It is best to slope the sand for debris to gather at the lower end of slope.
- The survival of fishes depends upon the amount of oxygen they can get from the water. The larger the water surface the better is the exchange of oxygen and carbon dioxide. If the tank is overcrowded with fishes, the carbon monoxide level becomes high and the fishes are forced to gasp at the surface.
- Fishes can survive in tanks deviod of palnts, but palnts help in saturating water with oxygen. Besides removing toxic carbon dioxide and preventing toxic substance formation in the water, they also add to the beauty of the tank. The choice of plants depends upon one’s taste and judgment. Groups or clusters are preffered than single stalks.
- Water may contain dissolved gases, salt, and organic matters. Thus rain water is more suitable than domestic one. Allowing the latter to stand exposed for several days makes it safe for use.
- Start with common abd inexpensive ones as goldfish or guppy.
When buying a fish, consider the following:
- Choose those that appear normal to its kind, with bright and glistening scales.
- Fins are spread out not carried folded to the body. Dorsal fins are held out.
- Lack of color does not necessarily indicate ill health. Most fishes tend to lose color when frightened or stressed or if the water is too cold. This is just a temporary condition.
- Prefer a fish that does not swim in an erratic manner or rubs itself against objecxt in the acquarium. It may be diseased or has parasites.
