for guppy fry? When changing water for guppy fry, we should choose good water, and the water temperature should be consistent with the water in the fish tank. When changing the water, gently pour the water into the fish tank to avoid the impact of the current on the fry. If the temperature of the new water is relatively low, it can be blended with hot water. One third of the water can be changed, not all of it, because the small fish can not withstand a large change in water temperature.
of guppy fry for water? 1. Temperature: The water temperature should be kept in the range of 18-34 ℃. Not too high, not too low. Water temperature should not fluctuate too much, which can prevent white spot disease and Saprolegniasis.
2. PH value: control between 6.5 and 7.5. The acidity and alkalinity of water have a great impact on guppy, and the change of PH value alone may make guppy fry feel tortured to death. Therefore, the number of water changes should not be too many, otherwise it will cause changes in the PH value.
3. Hardness: Guppies like hard water, and hardness of 10 to 15 degrees is the most suitable.
4. Concentration of nitrous acid: The concentration of nitrous acid in water also affects the survival of guppies. Water with extremely low concentration of nitrous acid should be used to feed them. If the concentration of nitrous acid is too high, it is very harmful to guppy fry. Fish tanks are closed, many fish friends have a relatively high feeding density, ignoring the importance of nitrous acid, not often testing water quality, nitrous acid content exceeds the standard and does not know, which eventually led to the tragedy of collective death of guppy fry.
