Hi! I recently got a ten gallon tank, got everything set up, and gave it a few weeks for the nitrogen cycle to complete. I just got a couple of fish (A small school of ember tetras, a few corydoras, and a Giant male betta) a few days ago, and I noticed that some of them seemed to be gasping and going up towards the top fairly frequently, so I bought an air pump for them. I just got it installed, and it seems to be working quite well, but I’m a bit concerned that the air stone I purchased was a bit too large for my tank. I was wondering what size air stone is generally recommended for a ten gallon aquarium.
