The water must be clean and clear. Everything likes a clean environment, and fish is no exception. Those so-called fat fish can grow up because there are many organisms and microorganisms in muddy water, and then there are many insects and food. If there is enough food, clear water is definitely the best. Because it is for domestic viewing, there is no shortage of food. There is no need to make a dirty environment for it. Besides, you have to watch it. I don't know what kind of frog you have. Some feed crickets, put them in front of them with tweezers, and eat them when their legs and beards move, but crickets are hard to find. Earthworms are the best feed if you don't find them disgusting. If you throw them in, they will eat themselves when they see themselves crawling. Tenebrio molitor is not bad. Frogs on TV are fed to Tenebrio molitor, which is sold in the flower and bird market, so it is convenient and not dirty. Also, don't worry that your little frog will starve to death. Cold-blooded animals have little activity, no heat production and little consumption. Generally, one meal can last for a long time.
