The past 2 months I have been experimenting with a microworm culture feeding my small tanks at home. So far the fish go crazy for it and I've had a lot of luck just adding bread and water.
So now to the title of this, my idea for @Cory is in his new pond/farm set up at his new home is to experiment with suspending a microworm culture above a few of the ponds. My thinking is it would operate as an autofeeder of sorts and if you can make the culture the correct size it wont overfeed. If anyone has tried this or has any reasons why it wouldnt work I would love to hear them!
