Some aquatic plants should be put in the glass bottle for raising tadpoles. Aquatic plants are not only for beauty, but because they can continuously absorb the carbon dioxide exhaled by tadpoles from the water and release the oxygen needed for tadpoles to breathe. Change water for tadpoles frequently and replenish oxygen constantly. Remove dead tadpoles and other food residues in time, and change fresh water every three or four days instead of well water. But tadpoles are easy to raise, so be careful not to put too many groups. If it's too much, even if the food can keep up, it's hard to raise and it doesn't need special attention.
It should be noted that
Don't make the water stink too much.
Generally, a smelly tadpole won't die. )

There are too many tadpoles.
Legend has it that they have toxins that inhibit growth.
Keep it in a fish tank. The density should not be too high. Aquatic plants, fish food or egg yolk can be put in it. You can also put some stones in the water to prevent it from drowning when it develops into a young frog.
Interspecies struggle, including food, living space, etc. Tadpoles sometimes release a toxin from the body, which leads to the death of weak individuals.
