Inverts for ecosystem tank

[Osse]

I have a natural style tank, complete with soil under the gravel. The soil must have come with planaria. I'm not against the planaria, per se, but what I want is multiple species of tiny invertebrates living in the detritus.

So, I'd like to introduce other inverts to compete with the planaria. I've found very little information about adding what are typically considered food or pests to natural tanks, to help round out the ecosystem. So far the best direction I can find is to buy live fish food and hope they breed. Which basically means tubifex worms or daphnia.

If you were building an ecosystem, what invertebrates (other than shrimp and snails) would you add to the tank? Will tubifex worms compete with planaria?

I don't know the species name but there's those long white detritus worms

Seems like there's a bunch of things called detritus worms, and NO ONE'S selling them.

Hit up a local Facebook group if you haven't already. They're not uncommon. I
practically guarantee someone in your area has a tank infested with them. It's just a matter of finding that person lol.
