is noise driving my cichlids crazy??

Just revived my 75 gallon tank. I have a powerhead at the bottom so I
have to use an air pump to feed it air. With only enough hose to set
the air pump on the glass top of the tank, the cichlids were VERY
unhappy due to the loud vibration. As soon as I got enough hose to
place the air pump away from the tank they got bright and chipper
again. I think the heavy spray of air bubbles may dampen the whirring
noise of the powerhead's impeller.

I have a 20 gallon tank with an electric blue johanni melanochromis and a
jewel cichlid. My setup has been running for about 3 months and my tests
show the water quality is good. Lately, they both have strange looks on
their faces and are acting somewhat deranged. I know in their natural
environment they dont have the BUZZZ and RATTTTLE of electric pumps,
filters, etc. and am wondering if all the 24 hour a day nonstop noise has

Consider that noise travels in water a lot better than in air and just put
your ear to your tank and you will be surprised at the noise and vibration
level.

I turned off the aeration pump which is the biggest offender at the risk
of
not having enough oxygen but with the hope of giving them a break from the
torture of the noise, though I still have a mini-penguin hangon filter
doing its share of vibrating. Any suggestions as to how to overcome this
problem? I thought of having a sump and doing all the filtration and
aeration done there, but if theres a better alternative please let me
know.
Thanks. Sleddog.

There's a lot of noise in Nature, too. Waterfalls, babbling brooks, boats,
fish noises, thunderstorms, that sort of thing.
I do consider vibration to be something the fish don't need. But since
water carries sound and noise very well, even a pump 50 feet away will cause
some in tank vibration. About all we can do is buy quality equipment which
is usually the quietest, and do all we can to isolate the tank from noise
sources.

sleddog,
when you say water is good what do you mean? the jewel comes from pH
neutral, where as the melanochromis come from the rift lakes therefore pH
should be 8.0-9.0 this could be the problem.

hey josh, my PH is 7.4, i didnt know the melanochromis needed 8+. Is my PH
harming both fish at this level? i did notice the jewel is looking more
depressed than her tankmate. i hate to separate them as they are good
buddies but if necessary i will, please advise, thanks.

fred, thanks for your story, it definitely magnifies my suspicion that
noise can torture cichlids, your idea is great, airline hose is cheap so i
will immediately move the airpump far away. ill report any changes.

I suspect that any noise which is constant will be tuned out like white
noise. You can see this by the fish's reaction to a power failure. They
react like the sound of silence is momentarily deafening. Irregular &
intermittent noises would IMO more likely stress them out.
