What is this

[Meganinez]

Bought some new live rock this was a hitch hiker. After a month it fell off and was floating around my tank. Caught it and tossed it in a ziplock. What is it? Anyone?

Bubble algae. Don't pop it or you will end up with a ton of it!

Looks like bubble algae to me also.

No. you don't want that stuff in your tank. it's a nuisance algae.
