So this morning I'm getting ready for work... I make myself a nice plate of eggs, bacon and a bagel with a cup of coffee... i go into my dining room and sit down and start eating. As i eat and enjoy my breakfast I'm watching my stingray swim gracefully around her custom 240g tank that goes through the wall between the living room and dining room... This tank is a 4' x 4' x 24" square with a center overflow. As I watch her swim to the far side of the tank (livingroom side) I hear something that sounds like a gun go off and watched as the water quickly drained out of the tank into the living room. At first i though it was a very bad dream... till the smell of saltwater hit me, and the tidal wave came around the wall and soaked my feet. I jumped up and started calling for my husband to come help as I'm looking for the ray. I didn't see her till she came swimming out from under the couch in the inch of water that was on the floor. so i quickly grab a 5g bucket, and a little bucket and start scooping up water, and my husband catches the ray. and from there a lot of phone calls were made and we got a company to come out and take up all the carpet and set up driers in the house, and other stuff to repair the damange. 
But I say all that to ask this... We had to move the tank to get to the carpet underneath, I thought it was a little odd that the piece that popped off causing the tidal was bowed, but figured it was due to the great force of it pealing off of it's seams, but when they moved the rest of the tank not even two inches it literally fell apart in their hands... by that I mean all the seams broke apart... My tank now sits in the garage in 6 pieces, but each of the side pieces are all warped to the inside of the tank. my question is this... are they supposed to bewarped that way and also, shouldn't the areas where the two pieces of acrylic were bonded together be rough?
p.s. Don't worry, the ray is doing fine in ghetto-rigged cooler and will be finding a new home as my husband and i are now scared to get a new tank.
