Thanks! A friend of mine was at Walmart and I asked her to check the dimensions. The stand is 29 1/2 inches lengthwise but my aquarium is 30 inches lengthwise. The guy in the dept said a half inch hanging over wouldn't matter since the weight of the tank should distribute once filled with water. Do you think this is safe or keep looking?
Yup it's fine. My tank hangs over the edge a 1/4" on each side just like your tank will. I think it looks better this way as the tank fits perfectly to the stand. I'm very happy with mine I think you will be too.
