I have had my aquarium for about 3 months now. I have 5 Tiger Barbs and 1 Red Tail Shark. There have never been bubbles floating around my aquarium up until about a week ago. I don't know why they are there or what is causing them. Obvioulsy they are not harmful but just wondering why they are showing up now and not before.
The only change I have made recently is to thier food. I had flakes and now I am giving them freeze dried medley.
