Goldfish Station

The two most important things to do with an already-operating fish tank are two of the most enjoyable. First, turn the aquarium light on and off every day. Light is important both for the fish and the plants. And as we have already learned, fish need their sleep. Second, remember to feed your fish every day. You need to do this at the same spot of the tank each time and around the same time each morning and night.

The most important thing that any fish hobbyist can do, other than these two things, is be observant You must closely watch the fish for signs of disease and watch their interaction to see if any are being picked on by the rest You must check the plants to see if any parts of them are dying; if they are, these brown sections must be removed at once. You must check the water temperature to make sure that it remains constant.

You need to examine the air stone, the filter and the heater to make sure they are all in working order. The filter may be experiencing some blockage, especially if you are using a box filter. The thermostat light should be on. Make sure the air stone is operating at maximum efficiency.
