The filter pump in the fish tank will affect the rest of the goldfish at night

No, for example, if a fish swims back, how can you swim back if you only have a memory of seven seconds? This is a literary parlance. The scientific statement should be that different fish should have different IQs, and the 7-second statement is not credible, for example, the fish we have are more intelligent, can know the people who feed it regularly, and do not respond to strangers 7 seconds may only refer to some specific memories, for other specific information, the memory of fish is amazing, like sea turtles.

Every year, they will return to their birthplace, salmon or something can remember the smell around the sound, the location, etc., for a lifetime, five or six years, or even ten years later, when they are fully mature, they will come back there to spawn, from this point of view their memory is still very strong, and in essence, their nervous system.

There is no qualitative difference with ours, so the memory should only be a quantitative difference. It won't affect it, because the sound of running water is louder, and I'm a large farmer. Hope to give good reviews.

For goldfish, a fish with a "three-second memory", they don't need to sleep for a long time (half of the brain) so the noise has no effect It's just that don't bother yourself Also, the pump can't be turned on for too long, and that frequency will be illuminated for a long time into some small effects (in fact, it doesn't need to be turned on for that long) hh

What's the matter, I've started raising goldfish, what do you want to ask me, I've been raising fish for more than ten years.

I can't bear it, because the body resistance of the whale itself is relatively weak, and the noise of the pump is relatively loud, which can easily lead to the death of the goldfish.

Fish can't hear sound, only the lateral line of the sensing organ can feel the disturbance of water ripples, so the noise of the pump has no effect on the fish, but it has an effect on people.

No, because the noise of the pump is still very loud, and the goldfish can't stand it under normal circumstances.

Generally, it will not affect the rest of the fish, and if you don't want to keep it open, it depends on the situation, and the density of the fish must be considered. If the density is large, it must be left on all the time, otherwise it will cause insufficient oxygen in the filter material, which will lead to the death of precious nitrifying bacteria. If it's a low density, it's okay. Brother pin.
