hi i'm trying to set up another tank and i have a 30 gallon long....but a 29 gallon stand....the stand is 31inches long but the tank is 36...will i be ok putting it on there with a little glass sticking out over each edge?
No, if you do that you'll have the danger of your tank overturning.
It will be much safer if you get a stand that will accomodate the tank, and not try and make something fit.
