currents? Parrot fish like slow currents. They are hybrids with defective mouths that cannot be closed and are less able to get oxygen and food from the water. When the current is fast, it will cause damage to their gills and affect their breathing. In slow-flowing water, they can not only breathe normally, but also find food freely in the water. So they prefer slower water flow.
for parrot fish? When raising parrot fish, there are many filter devices that can be used, such as barrel filter device, air-lift biochemical cotton filter, fish tank filter with shape, aquarium top filter and so on. What kind of filtering device is good should be chosen according to the specific situation. The barrel-type filtering device is placed outside the fish tank and has the advantages of good filtering effect, low noise and no space occupation, but the barrel-type filtering device is relatively expensive and is suitable for a large fish tank. The air-lift biochemical cotton filter
has the advantages of simple structure and low price, but the filtering effect is relatively poor, and the filter needs to be cleaned frequently, so the air-lift biochemical cotton filter is suitable for small fish tanks. The fish tank filter with the shape has the advantages of good filtering effect and beautiful appearance, but is not suitable for large fish tanks. The filter on the top of the aquarium has the advantages of small occupied space and convenient cleaning. It is suitable for small and medium-sized fish tanks.
