What are thoooooooooooooooooooose??

This is why I love MFK, always more and more interesting stuff to learn.
I stumbled on it by accident but it worked so I kept doing it. I’ve been feed fry with these worms on and off for about three years now.

I knew them worms to be not harmful and can be food for small fish, but to actually culture them and feed to fry is neat.

At what size can fry do this? Sounds like a very easy way to feed them good food!

Once the fry get to 1/4 inch to 1/2 inch they can start eating them without problems.
I have gave them to tiny fry and they try to eat th and some manage. They are larger then micro worms but not as large as black worms.

That’s awesome BIG-G

The closest I’ve come to doing that was putting my fry into my snail tank. I was raising snails at the time so I was heavily feeding the tank. I had a ton of those worms in there. It didn’t take the fry long to eat them. It was amusing to watch.

Like everyone has already said they are harmless.

I don’t know if anyone else has ever done this before, probably so but I’ve never seen it posted or anything.
I actually keep a tank just to produce these little critters.
Kinda like a worm culture, I harvest them and feed them to fry. They will actually gobble them down, they love them.
I’ve never had any problems doing this.
I just stir the substrate a little bit and get them floating up in the water column.
Take a fine mesh net and swish it around and catch a few then turn the net inside out and swish it in the fry tank.

This needs to be posted in my thread "fish foods, big list"

Do it to it brother! Copy and past or just write it up. It’s cool, I don’t care about credit for the idea or anything I’m sure it’s been done before, I just don’t recall ever seeing it.
It works though. Fry love these little worms

Interesting.While I have heard that many small fish enjoy the worms I have never heard of anyone culturing the worms just for that purpose.

I have a tank that for some reason they just multiply in. I just throw a couple sinking pellets every few days and it keeps them going.
I tried to get some video of some angel fish fry today. But I think they are still a little small for the worms. The fry just became free swimming yesterday.

dumb question of the day.. from where do these worms come? naturally in substrate?
i have a coule tanks that i feel like over feed but i have never seen them, the fry food idea interests me

Probably hitchhiking on plants/other material.

I get an outbreak of these worms every time my filters are even remotely dirty.. some tanks get them some don't. Depends on the size/type of fish being kept.

There is a difference between Planarian worms and Detritus worms.
Planarian worms are flatworms related to flukes and tapeworms.
Detritus worms are segmented worms related to earthworms and tubifex worms.
These in question from the OP are Detritus worms.
Detritus worms are far more common in aquariums then Planarian worms.
Here is a little additionally reading if anyone is interested.
