What in the world is this

[Obsessed]

Its starting to pop up all over the tank on the rock, little brown round/oval bubble looking things. I've been sucking them out and they keep coming back and then just found this huge one growing

Any idea?!

When you said "bubble-looking", I was ready to see Valonia bubble algae ... but those are usually a brighter green and shiny.

I don't know what this guy is - but I'll bump your thread to help you find out! (>_<)

Thanks Bruce, yeah definitely not the regular bubble algae. These don't pop, just kinda deflate if you hit them.

Snot looking bubbles makes me think of dinoflagellates. May want to check out info on it.
