Hydroids or Micro Featherdusters

[smd189]

Good morning. I just noticed these by the 10’s of 1,000’s in my sump. I don’t see them in the DT. They are extremely small hence the terrible picture. They appear to be small tubes with tentacles. How much of an issue is this? Any suggestions? Thank you.

- parameters appear perfect.
- coral, fish, shrimp, snails, etc appear fine.

They are feather dusters and perfectly normal and good. Leave them alone. I also have thousands for decades.

Thank you very much. Things have been calm for the last 2-3 months. Even seem to have depleted the flatworm issue but saw these guys this morning and started to panic. Thanks again.

They are filter feeders and are filtering your water for free.

Either micro feathers or spirobid worms. Both are good.

Spriobid worm tube look like the below. Feather duster tubes vary in overall shape a little but look like second pic. All from google.
