Chaeto plant critters

[Tang23]

I put Chaeto in my sump a month or so ago and now see little "critters". Is this something I should be concerned about? If it depends on what they are, I'll investigate further. Thought it was maybe live brine shrimp I fed, but they're not.

Thanks

Plants are known carriers for many things like copepods and worms. Most are harmless and good food for certain fish. Unless they are on the fish, I wouldn't be concerned. Most of those critters are actually eating the detritus so are beneficial.

Here's a video. They only seem to reside in the first chamber of the sump. Can I a fish or invert in there to take care of them?

It looks like a scud. I wouldn't get rid of them. They are eating whatever leftover foods your fish aren't getting as well as any other detritus.
