Microworms are another of my favorite foods to feed baby bettas, and they are a great food for juvenile fish of many species! They’re bigger than vinegar eels, but fish who aren’t quite big enough to handle baby brine shrimp can feast easily on these little wigglers.
Microworms don’t swim, they will slowly sink down to the bottom of the tank where they can be gobbled up. I recommend making sure some snails are present to take care of the microworms that the fry don’t eat.
These guys are incredibly easy to culture. Make some plain instant oats (I like a pretty thin consistency), let it cool completely and add the oats to a plastic container. Remember some air holes! Add your culture and give them some time to populate – you will be scraping them off the sides in no time.
