As for breeding, it is suggested to buy some fresh river shrimps in the market, then cut off the head and tail (the head of the river shrimp has a spear, so the head should be cut off), and lay them in the freezing layer of the refrigerator for freezing (each shrimp is separated by a little distance) to facilitate future breeding. Every time you feed them, you should replenish water in the original tank, 2-3 times a day. If it freezes into a lump, it is very troublesome to feed. Live food, loach, small fish and the like are not recommended.
Second, polyculture:
Zebrafish, although this personality is particularly family-oriented, is still fierce in the end. Unlike others, it looks fierce, but it is actually easy to mix. For zebrafish, keeping them alone as soon as possible is to avoid being bitten, but it is observed that it is very interesting to raise zebrafish in mixed culture as a child. Zebras and pike didn't have teeth then.
Crown pike, which is expensive, will be abandoned at first sight, but this kind of fish looks fierce. In fact, it is easy to be mixed with big fish to meet the requirements of similar size. However, it is best not to polyculture when you are young, but to polyculture when you are older.
