I feed my betta twice a day. I give about 2 pellets in the morning and maybe 3 at night. Is that too much? He's in a tank with neons, so I put in some tropical flakes for them, but the betta eats that as well. Normally I check to see how much of the flakes he eats to determine how many pellets to give him. Sometimes it's just 1. Is it a good idea to fast him for a day? In that case, I would have to fast the neons as well? How do you know when the betta has eaten too much, or is getting fat? Could someone point me towards pictures?
