Would feeding them a live fish cause them to get worms?
Why are we told to feed only a few pellets a day when they can obviously hold a lot more?
I thought their stomach was only as big as their eyeball!
It is a huge difference in digestibility. Pellets have all sorts of things that bettas really aren't able to digest. That is why you see so many instances of bloat in these fish. It is like trying to make a cat a vegetarian, it just isn't going to happen without making the animal really sick or die. If you are familiar with raw diets for dogs and cats that will make more sense than if you are still in the realm of feeding kibble.
As for worms, yes, they could. However, many feel that this is a risk they are willing to take in order to feed more digestible nutrition or they get their food from a reputable source.
I personally would not feed live fish because I couldn't find a good, safe source, but I gladly feed live worms, fruit flies, etc.
