Need help with dino microscope ID

[Velcro]

Looking for help IDing this dino strain. It doesn't seem to be toxic as I have not lost any snails and it is sometimes on coral long term without causing death

Getting a true ID is difficult with dinoflagellates as there is not of recorded info available.
Here is the best dino (well a lot of things) guide I have found so far.

Thanks for the link. To me it looks more like Prorocentrum than it does Ostreopsis

I don't really know what I'm looking at though :)

Got a picture at the next highest magnification.

It's the tip of the cell structure that throws me off for ID
I need to fit an electron microscope in my house :)

Whatever it is, it seems to be nontoxic. The only time it seems to tick coral off is if it blocks light too long. I don't see any dead snails. I was watching a turbo graze on it last night and he's healthy as ever.

Any idea what these sluggish looking things are in this (poorly captured) video?

I can't tell.
What are your objective powers?
Also what power is the eyepiece?

It's a super cheap kids microscope. I can only get it down to 10x objective using a 10x eyepiece
