1, using chlorine-containing tap water. Chlorine is a common disinfectant in tap water, but it will kill tadpoles. Countermeasures: Tap water should be dried for 2-3 days (chlorine gas volatilizes) before it can be used for tadpoles.
2. The water for raising tadpoles is not changed for a long time, and there is no oxygen in the water, which leads to the death of tadpoles. Countermeasures: according to the size of the water tank, replace fresh water every 3-7 days or equip the water tank with an oxygen pump.
3. Feed a lot of atomized egg yolk, bait, etc. , making the water very turbid, leading to the death of tadpoles. Countermeasures: Try not to feed fast atomized bait, or feed it in small amounts until the tadpoles finish eating. It is recommended to feed granular fish worms so that the water will not be turbid.
