Hi guys! I have had a 20 gallon tank since last December, and I just noticed tonight a small amount of water gathering around the edges of the bottom of my tank. It is all around the tank, not a specified spot. I will wipe it with a towel and it will come right back but it’s only the tiniest bit of water. Is this a beginning to a leak? Why is it all around the bottom of the tank and not just one spot? Could it be condensation somehow? A bit worried and wondering if I can leave my axolotl in the tank over night and deal with it tomorrow or if I have to take her out.
