Dino id

[JanBanan]

Anyone know the Id of this dinoflagellate?
Creates thin brown strings with air bubble

Looks like ostreopsis from the first video.

I agree ostreopsis, does it seem to disappear at night, then return in the morning?

 

[JanBanan]

Yeah they did disappear to some degree at night to reappear with the lights.
I tried a weekend blackout and hydrogen peroxide. Killed all my sps but dinos haven’t come back

Sorry to hear about the sps
