Little help identifying what this may be.

Not sure what this is.. anyone? Tank is roughly 6 months old

It is an aiptasia anemone. You'll want to kill it before it spreads, kalkwasser paste, Joe's juice, and Aiptasia-X are all good remedies.

You got your first aiptasia, now kill it! As started above by @bradleym . Don't try and do it by hand as it will send out seed and you will have little baby's everywhere.

Keep it simple:
Using syringe, inject either lemon juice or better yet. . kalkwasser powder mixed with tank water into a paste the consistency of toothpaste and inject into the very center core and it will melt away
