Help ID something on fish and glass.

Hi - I noticed these the other day but thought they were just little snail eggs or something maybe. Didn’t give it much thought but now I have way more on my glass (20+) and saw one moving around on my frog fish today so I got worried. This is the best pic I can get. They are much bigger than copepods and all have the same shape to them. When I tried to clean them off the class they swam around kind of wavy like. Any help with what these are? I’d be so grateful.

Here is a pic of one crawling on my frog fish.

These are acoel flatworm
They must be removed ASAP before they grow in numbers
These annoy livestock and smother coral blocking light for food source
Best method is to siphon as many as you can and you can add a 6 lined, lunare or melanurus wrasse typically eat these

Ok thank you. I also saw this article in my research and do see some on the new frogspawn and torch coral I just got as well. Is this the same pest you are talking about or totally different? I figured I might want to dip all the new corals I just got too. Thoughts?

Dipping always is a good preventative measure
