8. Feeding and Food nutritions
nefish: Tubi need to be chop before fed. Handling of tubi mentioned by itchy too, maybe itchy want to add on.....Change, no need to chop, had tried with few days old fries.

Water (Singapore)
In Singapore, tap water is the safest for guppies. Chlorine, chloramines and ammonia are added. The purpose of adding ammonia is to make the chloramines more stable.
Chlorine will evaporate when water is allowed to sit overnight. This process can be speed up by the use of aeration or adding anti-chlorine solution. Chloramines can only be removed with anti-chloramines solution. Ammonia can be removed by some of the water conditioner. |

Nitrogen Cycle
Ammonia (NH3) or ammonium (NH4) is produced from the breakdown of protein and is excreted through the gills (urine). NH3 or NH4 is also produced from decaying feces, food and, dead bodies, and decomposing plants. Ammonia is converted into nitrite (NO2) by Nitrosomonas (helpful bacteria). In turn, Nitrite is further oxidized by Nitrobacter bacteria into Nitrate (NO3). This aerobic process uses oxygen (O2).

Salt and minerals (freshwater)
Salt and minerals are important for biological functions. In freshwater, the concentration is much higher within the fish’s body than surrounding water. With the understanding of the process of diffusion, the salt and minerals will move out and water will move into the body. The excretory system must get rid excess water and retain salt and minerals. On average, Freshwater fish has bigger kidney and urine more as compare to saltwater fish of the same size.
Question 1: Removing fish feces will prevent NH3 and NH4 build-up? Question 2: Guppy needs salt? Last edited by angelo; 04-10-2008 at 02:25 AM. |

Water Change
Guppies can live without water change for sometime. However, this will subject them to higher risk in disease outbreak. Such as fin and grill issues. Maintaining high quality water will keep the guppies health at tip top. Guppy fry need more water changes than adult guppies because of higher frequency of feeding. Water change will enable fry to reach their best potential size faster.

1. Removing fish faeces do not prevent ammonia from building up as fish urine too. NH3 and NH4 build up only when nitrogen cycle kick in. without a working filter, you have only ammonia and no NH3 and NH4. 2. Don't know whether the guppy needs extra salt from us or not, at least not from me. They took what was naturally available in the water and I thought they were doing fine. |

Ammonia is NH3 and ammonium is NH4. With biological filter, will be converted into NO2 and in-turn converted into NO3.
As mentioned in earlier post, guppies do need salt. However, not nececssary from water that we add. They can obtain salt from their food. Question: What is the purpose of adding salt into guppy tank water? |

Disease are split into two big groups, one that can survive in salt water, and one that cannot. By adding salt, the bacteria and disease that can only survive in freshwater would not be present. If something happens, then we can eliminate some of the possible causes and act on the current situation. For example, changing back to freshwater, or other medications.
