There are semi aquatic freshwater earthworms that are also abundant in the river systems and rice paddies in Thailand. These genus Glyphidrilus earthworms are essential to the organic rice farming in Thailand but of course, you need someone to control the population in case it gets out of hand.
Betta Fish will happily hunt for Zooplankton, Crustaceans and other water-bound insects as their main diet since these are also very common in the rice paddies of Cambodia, Vietnam, Thailand and Indonesia.
Of course if there is a smaller fish that is caught unaware by the Beatt Fish, it can be its meal for the day. Remember that the Betta Fish has extremely sharp teeth which can be compared to a shark, it is just that they are so small that when they bite our finger it does not affect us.

What If Your Betta Is Sleeping all the time?
If your Betta Fish sleeps all the time during day and night then there might be several problems.
Your Betta Fish might be sick. A normal Betta Fish during the day is very active and always curious looking for food to eat and hunt. You have to observe some symptoms on his body:
- White spot
Your Betta Fish might be invaded by the Ick, a parasite that latches to body and especially gills. This is normally caused by introduction of new member in the community and the parasite infects everyone in the tank.
If there is a swelling of the body then it means that you are feeding your Betta Fish too much. The best feeding is just once a day and you should practice at least 1 or 2 days without giving food once a week to clean his body from excessive food. If you are feeding him all the time then it will lead into constipation and ultimately indigestion and will cause illness.
If there are noticeable sores and ulcers on the body then your Betta Fish might have infected by bacteria or fungus. This happens all the time if you do not follow the regular 25% weekly water changes.
The normal captivity lifespan of a Betta Fish is around 2 to 4 years. If your Betta has been with you around 2 years already then it might be slower than usual.
It will spend more time in recuperating and resting. It would be better to feed him only once a day since Betta Fish metabolism will be slower during old age.
He requires a lot of resting and sleeping and it would be good not to disturb him.
As i have mentioned before that all Betta Fishes have different personalities. Some are born fighters, some are born hunters and some are just do not like to hunt as compared to their wild counterparts.
If you have conditioned your Betta Fish with regular feedings then he might not be as aggressive looking out and scouting his surroundings since everything is provided.
Betta Fish that are pampered and well taken care might lose some natural instincts as compared to the ones in the rice paddies that are constantly on the lookout on the surface to hunt and prey on insects.
