Two Different Dinos?

[ShanePike]

These are microscopic images from two different locations in my tank. The first is from long streamers that grow, for some reason, on the baby stomatellas that have spawned in my DT. The second is from a similar looking material growing on my overflow. I'm pretty sure they're dinos, but are they two different kinds? They look different to me, but I don't trust myself to accurately identify what species they are.

The triangular cells are diatoms.

Thanks! I was just thinking about the pointed oval ones, though. A lot in that first photo look like they're filled with seeds, while others look basically empty.

Look like the same dinoflagellate shape. The granulation of the interiors may not be a sign of health.

ostreopsis dinos.
some internal dinoflagellate cell structure is often visible with good microscope images.

Thank you! I really appreciate it.
