Stresso, Tank stress Options

[CHLeong]

Hi Bros,
Would like to share with everyone what I am doing and investigating. I have been trying to understand the differences in environment for goldfish raised in a pond and tank. Noise is one area I am looking at and I understand that noise/vibration multiply many times in water media.
I am no scientist so feel free to rebuke my discoveries. As we understand that generally fishes react to the environment via their lateral line. So I placed my ear against the wall of my tank, and realised that they are living in a very noisy envirnoment. Vibration from the internal water pump, air pump, the sponge filter are generating a lot of noise. Its like blasting a mini compo in a bed room(tank) as compare to placing in a park(pond).
Bros, put your ear to your tank wall, off all equipment and realise how peaceful. Then turn on everything, do you find any difference?
Attach are pictures which I have made to reduce the noise in their environment.


I am in a middle designing a less stress tub for my fishes, that I will also share with everyone.

Comments?

I must confess when I read your post I thought you're too free.

I have never listened to my tank ever before. Out of sheer boredom I decided to try (but I make sure no one is around.)

OH MY GOD! You're right. It's so noisy! Those of you who have never placed your ear against the glass tank do so to experience it.

So I turn off the IOS's water pump first. Strange, the noise has reduced somewhat only. Next I turn off the air-pump and boy, it's near complete silcence except for the ticking noise made by the Auto-feeder!

In my setup, the bubbling sponge filters make the most noise. The air-pump itself is not even place on the tank but hang on a wall.

Since everyone has some form of aerating bubbles in their tank, I don't think the noise hurts the fish at all. I think this may have to do with the noise is a constant and, I'm not sure about fishes, for human our brain automatically filters away constant "white" noise. If you have a fan blowing at you now, you probably didn't notice its noise until I asked you to pay attention to it. So in a tank, the noise in it may be ignored by our fishes, but a sudden loud bang will definitely shock them.

In any case, does your modifcation to reduce noise and vibration helps your fish?

Thanks for sharing this very unique topic!
