If you observe and keep to the following basics you should not have to worry about dirty water. The basic rules of successfull fishkeeping are :- 1 inch of fish needs a minimum of 1 gallon of water. :- Every tank needs a permanently running cycled filter. :- Every tank needs at least 50% of its water replaced every week. Most tropicals should be kept between 70F and 85F. (heater needed). They should be fed in the morning and evening as much good quality food as they can eat in 15 minutes. Food must never be left to rot in a tank. It will poison the water. If you follow the above rules your fish could do well but if you don't I can guarantee that they will be constantly getting sick and giving you worries.
