Can anyone share with me how you maintain water at tip-top conditions? This incldue no of fishes in a tank, no of water changes in a week and by how much, put coral chips to buffer the water, put anti-chorine and salt whenever there is water change, daily washing of filter media, heater set at 28 degree, put lot of plants in the tank, put sand in the tank, let algea grows in the tank, uv for sterilization, periodic pp the tank or certain medicine whenever change water or at an interval, so on and so forth. If you maintenance your water in this way, how long will your fish fall sick, say 2 months or 6 months the fish will need for medicine for certain illness.

Does any particular fish that keep in this way lives for at least 1.5 year?
