I have treated this tank for hydra with Fenbendazole, so it's not affect this worm.

It's most likely harmless, what I do is take some filter floss and wrap it around a net pole then swab out worm's. So far it keep's the number's down then they just die off.

If you run a sand sub don't be so hasty to get rid of them.They help avoid anaerobic spots by "stirring" your sub without uprooting your plants.

Yes,it was in the sand substrate before, form kind of pipe in it.

 

I think this worm is algae eater, I have too much algae on the glass, that's why it breaks out.

narrow down to midges larvae.

 

Does it harm shrimp?

 

I will add sponge filter in the tank later to prevent it.

mayfly larvae or midge larve can harm shrimp, however usually it is in leaves.

 

I only have adults in the tank. no death found.

 

I was thinking about two solutions.

1, net out the shrimp and put in external breeding box, put couple small fish in it to clean it up.

2, siphon out most larvae. 

 

I will try two first.
