Where can i find live bait for my betta?

You can hatch your own mosquito larvae. Just set out a bucket with dechlorinated tap water and within a week or so you will see little red worms swimming around. Just take a net and scoop some out and feed it to your betta. Only feed him 4-5 worms. Betta's will eat ALL the live food that is present, and if you feed him to much he will die.
