But for the growth and health of fish, it is recommended not to raise too much.
A better scheme is a one-meter-two gas cylinder, without adding oxygen filling equipment, only using a filter barrel. In this way, the water body is quiet, the sound is small and the artistic conception is good. If there are parrots, it is recommended to keep only about ten if they are about ten centimeters long.
Fish tanks can be decorated with their favorite stones.
I hope it helps you ~
