I’m working on starting a fish tank. I have an aquarium stand from Walmart That I got ages ago and an Aqueon aquarium from Petco. I put my tank on the stand (the tank is empty right now) and I noticed that the bottom of the tank doesn’t fully rest on the aquarium stand. Is this a problem? Should I put something between the stand and the tank? I’ve attached a picture. I’d appreciate any help Someone can give me! Thanks!
