What should I do if the water in the fish tank smells like fish?
When the fish tank smells fishy, see if there is something wrong with the goldfish. Generally speaking, as long as there is fishy smell in the fish tank, the fish in this fish tank must be sick and traumatized, and you can see the change by careful observation. As the water quality turns white, some bubbles will appear on the surface of the bathtub, resulting in insufficient dissolved oxygen and lack of oxygen for fish.
At this time, it is necessary to check whether there are dead but invisible fish in the corner. If this happens, fish should be fished up in time, and then some potassium permanganate should be poured in for disinfection. 1 hour later, change the whole water again, then clean the cotton filter and add some antibiotics, oxytetracycline and other drugs.

Precautions:
The fish tank should have a good filtration system, and it should be able to filter fish feces, food residues and so on. However, we should not rely too much on the filtering equipment of fish tanks. We should pay attention to hands-on, often clean fish tanks, water utensils and filtering systems, and clean up the excreta of ornamental fish in time, otherwise fish tanks may become hotbeds of diseases and affect people's health.
In addition, attention should be paid to the growth of ornamental fish to prevent water quality and environmental pollution caused by sick and dead fish, and the dead fish should be fished out in time.
Small rooms are not suitable for choosing large fish tanks, and the choice of ornamental fish depends on the room. Generally, some small tropical fish can be kept in small rooms, and some large ornamental fish can be kept in offices, living rooms or larger rooms. At the same time, we should pay close attention to controlling the stocking density and feeding quantity of fish to prevent excessive feeding from polluting the water quality and indoor environment of fish tanks.
