bulging tank

[mfdrookie516]

A picture with a straight edge of some sort up against the glass on the outside would be helpful too, to show exactly how much bowing is going on... if you have a yardstick or something.

i have just had a good inspection of the tank and i think that it is the plastic rim of the tank that has changed shape slighty and its just my paranoia making me think the glass has bent. thats why the lid doesnt fit aswell anymore and its the plastic parts that i can squeeze in the glass doesnt move
lol feel a bit stupid, thanks for all your help sorry it was my fault
