Pest ID help

[MikeDesjean]

Hey all,

I founds these once before on a frag I was cleaning off a few weeks ago and found two more. They are fairly large compared to a copepod. Wounding if it’s a friendly iso or amphipod.
Maybe even an ID on that worm too lol. Hope someone can help!

They are amphipods
Worm looks like a small bristle or a dorvilleidae worm.

+1 on amphipods and dorvilleidae worm. Amphipods are beneficial scavengers while dorvilleidae worms graze on algae.
