THE TANK

The freshwater aquarium tank has to be the right size. The right size doesn't mean dimensions, but it is more about its size proportion with the number of fish to be raised and accommodated. It should be equipped with a filter system, heater, with artificial source of light in the cover. The tank is ready to house fish after it is filled with water. This is just the start.

THE BALANCE

It is important to have knowledge of the required "balance" fit for the fish. It means the population of fish can affect the emitted waste matter in the tank. Usually, these waster matters consume bacteria in the water. The cycle in the aquarium is continuously balanced by this important principle. It will take some adjustments and timing before putting up the next batch of fish. To avoid too much loss, it is advisable to add not more than five (5) in a month. It is important to observe the change in the water's clarity on a daily basis. This isn't tedious because feeding is done once or twice a day. It means, every feeding is followed up by some check-up routine.

WATER MANAGEMENT & TEMPERATURE

Changing the water in the tank has to be done on a weekly basis. The dirt at the bottom of the water has to be suctioned and removed. Chlorinated water and other chemicals to reduce water chlorination should be avoided as tank filler because it can damage and discolor the gills of the fish.

Unplug all power sources from filter and heaters to avoid breaking the glass tank as a result of temperature change.

If you intend to clean the water, then it is also important to consider cleaning the glass for sanitary and aesthetic reasons. The fish show significant behavioral changes and agitation when the glass isn't clean.

Tepid water mustn't be too hot or it will affect the good bacteria in the tank.

OTHER THINGS:

What was mentioned above are just the basics about freshwater aquariums. Remember that putting up one is all about creating a habitable environment. Therefore, other add-ons such as plants, decorative objects and other things may help in keeping the fish content in a tank.
