Trying to start out in fishkeeping as a family - the ideal spot for our aquarium is on a kitchen counter. Someone has kindly donated us a 30″x12″ approx 85L tank which I have placed there and have filled to check for leaks before sanitising, etc. Our washing machine is right underneath and although it does not touch the countertop, the spin cycle is causing the tank water to vibrate, I would describe it as buzzing on the surface. We use the washing machine daily on account of our family size. Now I don't want to keep fish in vibrating water. Is it possible to dampen vibrations and solve this problem? I am very keen to avoid having to find a different location if at all possible. We are currently considering Kribensis cichlids.
 
Rather than trying to insulate the tank from vibration, I would investigate why there is so much vibration from your washing machine. That amount of vibration is tremendous. Are the washer drum springs weak? That causes much vibration. Could you put the washers feet on some vibration absorbing feet? I doubt anything you put under the tank will help much. I have all of my tanks on a thick sheet of Styrofoam but I doubt that would help in your case.
 
There are two large issues. One is stress on the fish. The other is stress on the siliconed seams of the tank itself.

Tanks shouldn't move and should be in places with low vibration.

I'm not sure of the impact on the tank and fish, or whether I would take the risk or not. Probably not. The idiot in me wants to suggest that as a family, you ring out your clothes by hand and enjoy the extra exercise. Think of those huge forearms you'll get.... However, I suspect not....

Kribensis are one of my favourite fish and me and @GaryE have swapped messages on them before. I believe they hold a place in his heart as well

In my own personal experience, my Kribensis males who breed are more aggressive than my male convict cichlids who breed, and that's saying something. A male breeding Kribensis in my experience will expect no less than two foot of space, or more, with no other adult fish in. My experience might be extreme, Gary might say different.

The reason I bring it up, is that Kribensis breed quite easily. You may have to rehome or make a tough decision if you get a group of them and a pair forms.

30" x 12" footprint, I guess is possible, in my opinion for a small group, but I'd rather 36" x 12" (I am sure many others will say 30" is enough). Also in my opinion, I like to leave the bottom 1/3 of the tank just for them, so no bottom dwellers for me other than my Kribs (ideally). Unless it's feeding time, I hardly ever see a kribensis above the bottom 1/3 level of a tank.

One issue I have had, what about you @GaryE is I have often needed to add dither fish in a Kribensis only tank, as I've found otherwise they will mostly congregate in the pots/caves. Don't want to complicate things for you, you've put loads of time and research into your project!!!!

They should always have pots/caves for me, even if that means sometimes you don't see them loads (but you will see them if they are settled)

Amazing fish, the kids will probably love them.

Try putting a piece of polystyrene foam underneath the aquarium to help reduce vibration. If it doesn't help you will need to find somewhere else for the tank.

The vibration is unlikely to affect the fish but as Gary mentioned, it could damage the tank by stressing the silicon seams (glue holding the glass together). If the silicon gets stressed the tank could leak or a pain of glass could come away.
 
I'll add - kitchen tanks often get cooking film on the water, as well. I'd consider other options. Fish that originate near rapids problem cancel out rumbles, but vibrating tanks break.
 
I can't imagine having a washing machine in the same room as the dishwasher.
Getting tighty whiteys out of the silverware bins would be one thing, but a griddle wedged into the washer? What a nightmare!🥴
