What looks to be a hairline crack in my tank

[meldogg]

I have a 3 gallon tank and it looks like it has a hairline crack going up the side of the tank. It is only on the outside though. I can feel the crack but it is very small and I can’t catch my fingernail on it or anything. What should I do? Do I need to purchase a new tank? Anything helps.

Is it really a crack? Or just a scratch? If it is a crack then you need to drain that tank asap

I would get a new tank i
I wouldn't trust it if it is a crack.
