| How Strong are Fish Tanks? This may sound like a silly question...but will a fish tank ever break if it has no cracks? When I first got my 29 gallon tank I noticed a scratch on the back on the tank. It starts from the bottom plastic and goes up straight for about 4 inches. It seems like it got scratched when the tank was being made and does not seem to be very deep...no leaks as well. I marked the spot to see if it grows, but do you think it will be ok if I put some silicon on it? I am tempted to buy another 29 gallon but I dont want to spend money if everyone thinks it is ok. Thanks! |
