Help! - Possible Cracked Aquarium

[nzafi]

I went to feed my rhom and I noticed what looked like a possible crack in the lower right corner. I definitely feel something on the outside of the tank, but nothing on the inside. The tank is against the wall so it is hard to tell. Attached are pics. Any thoughts or helpful tips?

I am guessing the only way to tell is to drain the tank and move the tank. Do I call the manufacturer? I only bought this tank in Dec 12/Jan 13.

It's difficult to tell from your pictures if that is a crack or not. Can you drain most of the tank so you can move the tank and stand away from the wall to check?

put your finger on the crack and see if you can feel it or not. Take it to the manufacturer...

I am going to mark it and see if it grows at all. You can feel there is something on the outside of the tank, but when you put your hand on the inside of the tank it is smooth. I am thinking it could either be a scratch or excess silicone looking at it again. If it was really a crack I would expect it to be a bit rougher but also be able to feel it on both sides of the tank.
