Any ideas?

Don't know any other way of describing this except by saying its a redish-purple bubble looking thing with orange spots. It's been in my tank for a while. It grew in size and then stopped and has stayed the same for a few weeks. Any ideas?

I have no idea what that is, but im interested to hear what it is. Its pretty cool looking.

Red bubble algae? Google it

Could it be a sea squirt? Possibly look that up and see if it matches.

Very strange results when I searched the images on google. Most of the images look like the normal "run of the mill" red bubbly slimy algae. There were a few images that looked very similar to what I have and when I went to the site that referenced the image they were also confused.
