I did a thorough cleaning yesterday of an old 20 long that I was going to get new fish for, and I left it out overnight in my driveway propped up against a fence to dry. When I came home from work today, the tank was still in the same place, but with a crack going from about halfway up the corner to the base of the tank. If it had fallen and cracked, then it would have been completely on the ground. I think it was the neighbor kid, cause he frequently comes to play with our basketball hoop without permission. Maybe he thought I wouldn't notice?

Is there any way I can fix this? I was going to reseal the whole thing anyway, so I don't mind doing repairs, but I don't want to go to the trouble if it's not going to work. I do think the glass is cracked all the way through, but nothing has actually fallen out.

Thanks ahead of time.

umm. aquarim sealiant it on both sides? kinda tack but 20 gallon tanks arent thooper chear either.

You'd have to replace that pane of glass.
Here's a good article on How to Reseal Your Glass Aquarium.

That's what I was afraid of...

a 20 gallon tank itself isnt really that expensive, if you alrady have all the trimmings....

when i shattered mine, i replaced the tank only for $10.99 (on sale @ petsmart)

Psh I'd make the obnoxious little kid pay for the tank!! lol.

I would but for that darn burden of proof.

This tank/glass box is now for sale/trade/whatever else in the buy/sell/trade section.

Edit: It won't hold fish, though. It'd have to be for some other kind of pet.
