1, frightened
If It is a normal phenomenon that the parrot fish that are raised at home get together and sink to the bottom and do not swim or eat. Because parrot fish are very timid, if they are not familiar with the surrounding environment, they will hide at the bottom of the fish tank
and reduce their sense of existence. This kind of parrot fish will return to normal when they slowly adapt to the environment; The noise is too loud, which makes them afraid, and they will hide at the bottom of the fish tank, so the owner needs to raise the parrot fish in a relatively quiet and dark place in the room, so that the parrot fish can feel safe.
2. The water temperature is too low
The parrot fish does not swim Gathering at the bottom of the fish tank may also be caused by the temperature being too low, because the parrot fish feels that the most suitable temperature is 25~28°C. If the temperature is lower than 25°C and the water temperature is in this low temperature state for a long time, the immunity of the parrot fish body It will drop, so there will be a situation where you don’t like swimming and sink to the bottom. At this time, the owner needs to use a heating rod to adjust the water temperature, maintain the water temperature between 28-30 °C, and let the parrot fish body return to the adapted temperature. After about a week, the parrot fish will not sink to the bottom. Adjust the temperature back to the temperature and the growth of parrot fish.
3. Enteritis
If only some parrot fish appear The phenomenon of sinking to the bottom is likely to be caused by them suffering from enteritis. Generally, it is because the food fed by the owner is not clean or they are too full, resulting in food accumulation in the body and not excreted in time. After a long time, bacteria will breed and infect the intestinal tract and cause enteritis. If this is the case, the owner needs to immediately replace all the water in the fish tank, and then sprinkle an appropriate amount of oxytetracycline or gentamicin in the new water to perform medicated bath treatment on the parrot fish; the owner can also add water in the water Added vitamins to improve the resistance of parrot fish.
