When the current is too big, it will feel afraid. The reason for its fear is that the impact of the current is very strong. Fish are small in size, weak in strength and limited in resistance. Too much water will make the fish unable to control their bodies and can only sway with the current. In this case, the fish is insecure. However, if it is only a small stream, it will not affect its mood. Especially when the fish tank area is relatively large, small water flow will not bring too much feeling to the fish. The swimming and rest of the fish will not be affected. So when the current is very small, the fish will not be afraid. Only when the current is too strong, it will be afraid of the current.
When raising guppies, they usually choose a relatively static water environment. When the water flow in the environment is small, it can also adapt. However, it is not allowed to keep them in the water where the current is relatively fast. As mentioned above, too much current can give fish a sense of fear. It is not conducive to its growth and development to keep the fish in a state of fear and alert for a long time. And when the current is very fast, the fish can not swim normally. In the fish's rest time, it will disturb its rest. Therefore, guppies can not be kept in the environment where the current is relatively fast.
