What fish can survive in a fish tank without an oxygen tank?

You can change the water to clean the stones. You can use a small amount of soap to wash off the dirt, but you have to wash it thoroughly, otherwise there will be residual soap in the water and the fish will float around. It's not good. If you are still worried, you can sterilize it! I would recommend using the original method to roll the stones with water. Bacteria will die at high temperatures, so you can ensure that there are no bacteria. After that, wash them with cold water to cool them down and put them back into the tank. But if you are really worried, you can also put the rolled stones in the sun to ensure that they are very, very clean and sterile. After that, you can wash the things in the tank, including the tank. If you have patience, you can use the same method as the stones, but I don't recommend rolling glass with hot water. After all, high temperatures will cause certain damage to glass. Put everything back in place after use. Pour filtered, oxygenated, and bacteria-rich water into the tank and put the fish in. While doing this, you can first put the well-preserved water into a clean container and put the fish in it first.

3. Fish farming experts, please take a look

It should be the grass goldfish, also known as the golden crucian carp, which is the ancestor of goldfish. Generally, there are two types of fish raised in park lakes: grass goldfish and koi. This kind of fish is very easy to raise, easier to raise than goldfish and koi, and is not afraid of low water temperature. It can be fed with tropical fish feed or goldfish food, and it only needs to be fed once every two or three days. Add a little coarse salt to the water, and it is best to put the fish tank in a sunny place, so that the fish can be healthy and retain its color. (The first floor is really ridiculous, there is no hybridization between goldfish and koi.)
