Last night around 1:30am I noticed that there were a lot of bubbles on the left side of the tank. They were about an inch thick and I have no idea why they are there. I have a male Crowntail Betta and he is in a 2 gallon tank. He also stays flared up alot and is always moving around. I dont know if that has anything to do with it but alot of info is better than not enough right? So whats going on with this fish lol
