2. Small fish prawns: For some carnivorous fish, they don't like to eat ordinary fish feed, and small fish prawns are their staple food. It should be noted that when feeding fish, it is best to take out the fishbone and remove your head when feeding shrimp, so as not to cut your stomach. In addition, in order to ensure that you will not get sick after eating it, it is best to do a good job of disinfection.
3. Water plants and algae: Many omnivorous and herbivorous fish prefer to eat water plants and algae, so they can be cultured in fish tanks, but not too much, otherwise it will occupy the growing environment of fish and even affect their survival.
