Day one of the potato - snails have found the potato and are preceding to tenderizing it with their slime trails. Two small worm clusters have formed along the outer edge, but these are not newly hatched, most likely they're free swimming worms in the water gathering together at a new food source.
I was able to get a close up in their mouth parts, it reminds me to tube worms found in the ocean, they would sway in the currents with their mouth open to filter feed on micro organisms, I will note that yesterday's tiny worm didn't display this behavior, they may be too small to be able to eat single cell organisms and need other foods.
I need to set more nursery tanks to test out food sources for the babies, this may be why most people who culture the worms don't notice when they get babies they might not be feeding the foods needed to raise the babies if they're filter feeders, my tub currently has yeast and infusoria moving around the tubs in the currents created by the air stones plus a lovely amount of protein rich snail slime and essential BB covering all the surfaces.
Fair warning if anyone is Following this thread, I can't stop myself from taking baby photos, I'm too curious about this process and annoyed that of all things this is what you can't find on the internet.
