Tropical - Fish - Pictures .com

This is a tropical fish site for all tropical fish enthusiasts from beginner to expert. It has some nice tropical fish pictures and will hopefully have something of interest for all freshwater and marine fish keepers. These tropical fish pages provide some information about some of my favourite fish, along with tropical fish pictures of them. I have kept fish for many years now, ranging from community to marine. Over this period I have been drawn towards catfish, and the cichlids, which I must confess, through there antics have become my favourites. I now keep African and American cichlids, along with some catfish and plecs.

Water Quality

H2O is the chemical representation of water. But aquarium water is much more complex than an oxygen molecule bounded by two hydrogen molecules! Fish spend their entire lives in water, and its quality and condition is a big factor in the aquariums success or failure. Water quality can be defined by the correct level of oxygenation, temperature, beneficial organisms and the absence of irritants, harmful chemicals and disease. These factors can all be controlled if the following water conditions are kept right

  •     pH: pH is the level of acidity/alkalinity of the water. A community tank is best kept at a pH level of 6.8-7.0. pH kits are readily available and can quickly tell you what pH your tank is. Any variations from the norm can be easily corrected. Sodium bi-phosphate is used to increase acidity and lower the alkalinity and sodium bicarbonate used to decrease acidity and increase alkalinity.
  •     Nitrate and Nitrite: A high amount of these pollutants can be detrimental to the health of your fish. Regular partial water changes of approx 15%, along with good filtration will keep nitrate and nitrite levels low enough for good fish health. These pollutants come from fish waste.
  •     Hardness: This is the concentration of chloride, sulphide and bicarbonate salts present in the water. This is generally not an issue if water treatment is used or rain water is utilised. Most fish prefer a hardness of less than 8 degrees of hardness.
  •     Salinity: This is measured as specific gravity, which can be obtained by and inexpensive hydrometer or ask you pet shop. A reading of less than 1.25% is ideal. A little sea salt in the tank can reduce the chances of disease.
  •     Temperature: This needs to be maintained at approximately 24oC or 72oF +/-2oC. A little warmer 26oC will increase the chances of breeding, make your fish more active and help reduce the effects of disease.
