Microworms

Are they really only for fry or will grown fish eat them?

Most fish up to 4 inches long will eat them. I used to feed microworms and newly hatched brineshrimp to my adult rainbowfish. It gives the fish something to do, chase small food

If I feed heavily enough, even my pearl gourami will eat them, rummy nose tetras too. Bolivian rams are confused what the others are eating. And if they fall (and they do fall to the substrate eventually), the corydoras have a lovely time eating them. They work best for small fish though, 3-4 cm or so I would say. Or you have to make the cloud heavy enough.

I'm not feeding them to fry. I got mine for my pygmy corys. I never really see them eating the grindal worms that I feed. They love baby brine shrimp though. So I think maybe something smaller will suit them.

Success! I just checked the culture I started on 3/14 and they're crawling up the sides.

The original idea I had was to have 4 cultures going. I'd rotate in a new one every week. But these worms are prolific. That would be way more than I needed and a lot of unnecessary work. So I cut it in half. Two cultures going and I rotate in a new one every two weeks.

My microworms have been going well.
Question. When I make my cultures, I rotate between instant mashed potatoes or oatmeal. But either way, I sprinkle dry yeast on top. Has anyone tried nutritional yeast?

@AbbeysDad might know. I'm pretty sure he used yeast in his worm cultures.
