Found red coral looking thing on my tank

[Civicman86]

So I was doing some cleaning to the tank and I noticed this small red finger like creatur on the glass. I went to my gf's to get a camera and now he is gone. I made an enlarged sketch of what he looked like. (looked alot like a torch coral just on a very small scale, maybe 2cm long). Anyways the bottom of him had like a clear bubble looking type thing.

Anyone have any ideas what this might be?

Also it was solid red, no black lines, I just did that to give the tentical things more definition.

It could have hitchhiked in on setup and you may never see it but in this case you did.
