HUNDREADS of black miniworms.

[Bug_Power]

I just took a look about 10 minutes after the lights went off. I've been adding a cup of sand from established tanks to make a diverse sand bed. I just saw HUNDREADS of tiny miniworms. Look black in color, all over my sandbed. Any ideas?

Any possible way you can turn the light on real quick and take a pic?

[Bug_Power]

here ya go, you can see them on the glass.

Could be small bristleworms. If that is what they are its a good thing. Thay are good detritivores.
