Tiny creatures on the glass?

[SuperReefNoob]

Wondering if anyone can ID these little creatures, just tiny little blobs sliding around on the glass...

Amphipods?

Flatworms of some variety

 

[SuperReefNoob]

Acoel flatworms. While they are not harmful as red planaria, they in numbers can smother bases of coral and block the needed light for production of zooxanthellae which is their energy source.
Removal can be accomplished by siphoning them with a 3/8" tubing into a nylon stocking and discard
OR
Add a wrasse such as Yellow coris, 6 line, lunare or malanurus OR even a springieri damsel which will eat them

With the number you have, for the next 2 weeks you will have to look for eggs and scrape off as there is likely some and would be future acoels. Eggs are really tiny

agree with Vetteguy.
I had/have these as well.
My tank is 4 months old and thee appeared two months in. They come off when I scrape the glass, but apart from that I have tried to stay on the 'relax, it s a new tank' way of thinking.
The amount I now have is a 1/4 of what I used to and still coming down.

Don't know much about your tank, but patience could help here, unless there are so many that they are causing problems.
