I had a few questions about my new betta fish, right now he is living in a 2 gallon (aprox) tank with no filter or anything. He started blowing bubbles and I was wondering what that was about? Now I can't tell if he is sick or normal...? Sometimes he will just hang there motionless, right now he is resting on the bottom (on the gravel) every once in a while he will do that. Also, how do I get food out if it drops to the bottom? A few peices have fallen to the bottom and I'm worried about them, about how many pieces should I worry about?
