Possible to get blackworm 'culture' growing in tank?

I currently have a 65g tank that is going to be populated by mostly small fish, and I am wondering if it's possible to somehow get blackworms to reproduce and thrive in my aquarium.
I'm using black sand which will have lots of dead leaves on top of it, and there will be plenty of moss soon.
If I place the blackworms under a moss clump where the fish can't get at them before they burrow, do you suppose they would manage to survive and breed? I know they're basically scavengers... I imagine that my fish would love having live blackworms occasionally wiggling up out of the sand for them to hunt.

blackworms like to feed with their heads in the muck and their tails wiggling in the water. If you have very few fish and a lot of blackworms yes you can get a culture going.

In my tank all of the inhabitants hunt until they are all gone. An ounce takes about a week to disappear.

As far as I know, not possible with bottom feeders. Corydora will literally bury their heads to get at the worms. And loaches dig naturally. Fun to watch but not good for the worms. I put about a pound in my 125 gallon, no idea if they are still there or not. I know they lasted at least a month though, now they may be down in the mud??

I put some in a 20 gallon with only a few guppies, danio and neon tetra, I think they are still surviving in there.

I use a ten gallon for my worms, and take out a few when I need. I double it up as a daphnia culture tank in the winter as well. Black worms populate very slowly so I don't ever have a huge excess

Fun though and I love thinking their somewhere in my tank.

2 adult kribensis cichlids devoured over 100 red cherry shrimp in a 55g within 72 hours.

I'm going to have rams, checkerboard chiclids, a goby, and a couple of darters for my bottom-dwelling fish. Do you think they'd get all the blackworms? I've never seen any of them dig.
Hmm... I have a female betta who doesn't quite know when to stop eating, do you suppose she'd eat herself to death on blackworms? If not, I might as well try once the tank is all planted and leafed up. At best, I get a blackworm-populated tank and at worst, my fish get treats for a while.

could you tell me how you go about doing this? I'd like to start providing my display tank with live food. so having a single 10g act as a breeding ground for these things would be fantastic.

i'd greatly appreciate it

I heard my LFS owner talking about how he with put a pot with gravel in the aqarium and the worms on that, then like was said before there tails stick out and are munched on from then. Whether they reproduce i dont know, just something i heard recently and maybe is some use
