Cracked tank: Does this pose a threat?

[Potawato]

Well tonight I discovered a crack in my tank, but it's probably the best kind of crack you could get.

I know it's hard to see but the crack is inside the red circle, the white line is the bottom of the top rim. The crack doesn't go down the tank, its just that corner that broke which you cant even see from the side of the tank since it's above the rim level.

Do you think I should worry about this?

What size tank is it? I would watch it and see if it gets worse.

You're probably quite lucky that it cracked at the top like that. If it travels from the top to the corner there I shouldn't think it will travel any further. Like Maha said, keep an eye on it just to make sure it doesn't leak. If it's quite small it be even be worth removing it and gluing it back in with fresh silicon.
