In fact, raising tadpoles is like raising a pot-bellied fish. The jar should not be too big, preferably not more than one foot (30? ); Even if it's a container that won't leak! The biggest difference between keeping small fish and tadpoles is that the former can be kept for a long time, while the latter usually becomes a small frog in 1 ~ 2 months. Therefore, you don't need to spend too much "gorgeous" equipment and furnishings; Unless, you raise frog tadpoles (tadpoles for more than half a year), or you raise small fish aquatic plants by the way. Otherwise, the "luxury house" that has been painstakingly renovated will soon be revoked!
Therefore, raising tadpoles only needs a "bare jar" (that is, empty basin water); If you think this is too cruel, just lay a layer of fine sand on the bottom and put some strong aquatic plants, which is very advanced. In addition, when collecting tadpoles, you can observe the original living environment of tadpoles a little. If it is caught in a still pool, it can be raised according to the above method. If tadpoles are caught in flowing water, it shows that the tadpoles have a high demand for dissolved oxygen, so an air pump should be prepared for them to minimize the gas output and avoid excessive water flow.
Prepare another basin for changing water.
The most important thing to pay attention to when raising tadpoles is the water quality. There are many factors that affect the water quality, including the number of tadpoles, the type and quantity of feed, the frequency of feeding and the layout environment. The most direct way to maintain good water quality is to "change water frequently", but how often is it changed? Changing water too often is also very troublesome, just change it every 3-5 days! When changing water, you only need to pour 2/3 of the water, and then add the aerated tap water to the original position. It is suggested to prepare another container for water aeration, and then fill it with water after each water change for the next water change. But the worst water quality is usually at the bottom, where there will be a lot of feces and inexhaustible feed. Therefore, when changing water, it is best to suck up the sediment at the bottom as much as possible to effectively improve the water quality.
Therefore, under such a frequency of changing water, the number of feeding times is determined. Although tadpoles can't be eaten as much as possible, they can't be given too much at a time, which wastes food and easily pollutes water quality. Therefore, according to the feeding times, different amounts of feed are put in; With a little observation, you can eat almost 2-3 times a day every time 10 minute, or add it slowly until the tadpoles stop eating. If you raise it at your desk, you can also adopt the method of "small meals and more meals", but only if the boss does not object to raising it first.
As for the number of tadpoles (it should be said that the density of tadpoles), it is best not to be too much. In this way, feces will increase and water quality will soon deteriorate. Secondly, living too close can easily lead to diseases and poor health. If you keep some big tadpoles, you should keep them sparsely and leave room for them to grow. Of course, you can only raise a few, and you don't have to change the water too often!
Common fish feed
Of course, if a frog wants to grow well, it must be provided with proper nutrition, that is, it must be fed. The simplest way is to use "fish feed", which is easy to buy and easy to feed. However, there are many kinds of fish feed on the market, each with its own characteristics. Which one should we choose? There are several principles to choose from:
"Quantity", as I said before, tadpoles will end in about two months, and it will be wasted if you buy too much at a time. If you have fish, you can use the same feed.
"Characteristics", after the feed is put into the water, some will float and some will sink. Observe in advance which water layer your tadpoles like to feed on (surface layer, middle layer or bottom layer), and then buy feeds with different characteristics.
"Ingredients", it is not easy to judge the quality of feed directly by the label of ingredients, but you can choose feed suitable for general fish with balanced nutrition.
"size", feed that is too big can't be eaten immediately, and it can only be eaten after soaking thoroughly (otherwise it needs to be slightly ground); If the feed is too small, the feeding efficiency of tadpoles will be greatly reduced. Of course, it needs a little observation before they can choose the right feed.
If you suddenly run out of feed, or occasionally want to change your taste, you can choose "rotten vegetables" (boil them, don't put them in! ), making tadpoles easy to scrape. If you find it troublesome to cook every time, you can cook a little more at a time, then soften it into green vegetable balls of moderate size, freeze them, and take them out one at a time and put them in water. After a while, tadpoles can eat. In this way, tadpoles can grow smoothly through interaction with feed!
Because the resources of a pond or a water area are limited, when the population density of tadpoles is too high, the average resources will decrease and the survival of all tadpoles will be threatened. So tadpoles will produce toxins, poison the weak individuals and leave the strong individuals, so the population density will be reduced, which is conducive to the continuation of the population. So goldfish and tadpoles can't be kept.
