Something strange is happening since I did my last water change a few days ago.* I have a 55 gal. tank that since the water change has started making strange noises.*
It's not a constant noise, and it sounds kinda like a loud, tap, knock, bump, creak?* I don't know, but it's annoying.* I've looked all around the tank with a flash light, checked the filter, airpump, everything I can think of, and I can't see anything out of the ordinary.* I can't even tell if it's coming from inside the tank or outside.* Like I said, it's not a constant noise.* Just every now and then I'll hear this mysterious knock, bump, creak coming from the tank.* It doesn't have any kind of rhythm to it, it's like:* bump, several seconds later another knock or bump, or sometimes several in a row.* It's driving me crazy!!!

Does anyone, anywhere, have any idea what this noise is?

Start with the moving parts. What kind of filter is it. if it uses a standard impeller, they make a knock sound if they get stuck for a sec or get air in them.

Could be the stand settling if its wood. Could be the structure of the tank is flexing. (that last one could be a real problem if it proves o be true)

Anyone ever had a tank fail?? that's my worst nightmare.

My tank is cracked now does that count as failed?

um

Yep.. yer done.. go replace asap. good news is all the stuff should transfer with some ease. don't wait, you'd be surprised how much damage 50 gallons of water can do.

My tank is 10 gallons and my dad and I are getting a new tank today. Should I wait to cycle or not?

For the haunted sound I have no idea.

if you have a hob filter I bet it's that making the noise. The moving parts get screwed up sometimes, or something could be caught in it. I had a filter that used to make the most awful clicking racket until I trashed it.

Sometimes fish can make a noise while eating or browsing the tank. My cories have made noises when they made the gravel push into the glass, and my bala sharks click when they eat all the time. Other than that I suppose you could check the impeller on the filter for anything, sometimes snails will get into mine and it will make a noise as their shell is crushed.

Oh yeah now htat you mention it my Cories make noises too. Sometimes if I scare them (they're super flighty Pygmies) they go crazy and start dashing around the tank crashing into everything, and they make a sort of vibrating noise. It's really wierd. Maybe it's their fins beating super fast?

all night i can hear my convict smashing gravel,
eating shrimp and craw fish,
it might be nothing,

What floor do you have your tank on? Could it be upstairs or on a floor that isn't cement and could it be your floorboards or support joists creaking? That can happen and you wouldn't want your tank to fall through the floor and crash down. What a mess it would be! Even a small 10 G tank can weigh over 150 pounds! If that isn't it and it isn't what others have suggested, then GOOD LUCK!

It sounds like a problem we just had with a filter in one of our 10g tanks.. where the intake tube sticks into the filter had gotten clogged some with gravel dust and was causing it to make weird noises at random times.
