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

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
