Need help identifying this

[TrevorL]

So I have been letting my tank run with the lights on a certain time frame cause I got a clownfish. I was wonder what this brown bubble looking thing is because a couple of them have popped up around the tank and I don’t know what they are. (Yes I also know my rock is very green with algae I’ve been meaning to go get some turbo snails to clean them off.)

Well....it doesn't look like dinoflagellates or diatoms to me. Have you tried to touch them? Are they squishy or hard? Can you suck them out with a siphon tube?

I haven’t tried touching them yet but they are holding onto the dock but are going with the flow of my tank
