Why do i have bubbles on the inside of the glass on my biorb fish tank?
its ok, its just air bubbles and fish need air more than water, they can stay in the same water but they need new oxygen in the air, so thats giving them more air and they will live longer because they do need air to live, a 5 foot long fish squished in a 5 gallon tank would have a miserable life but it would still live because of air in the tank and its because its like a circle shape and the air cant get out of the top of it because it getting stuck on the walls
