Is this dinoflagellates?

I’ve searched online on what steps to take but I want to hear from you folks here. Note: My water change is set for Friday ( weekly ) 25%.

Thank you in advance.

I was a bit worried about my Toadstool Leather for a while. It had been three weeks since I’d seen its neon green color, and I thought it might be dead, but it turns out it was just shedding! 🤣🤣 As a first-time reefer, I’m learning as I go, and it’s been an awesome experience!

Got back from my 3 day vacation and came home to Remi ( anemone ) slightly bigger and he moved. Full of excitement so much that I was fumbling on my own words lol . Enjoy the video, I sent this to my mom who loves my new hobby .

Pulsing Xenia is no longer pulsing. Any advice here ? Thank you.
