Baby bristlestar or aiptasia?

[Picassoclown]

Hey everyone. I just received blue hypnea from Topshelf and while observing it, I noticed there was a huge colony of bristlestars, which I do not mind, but i found these right after I put it into my tank. I do not know for sure if this is aiptasia? The dark spot on it looks like the body of the bristleworms I found. Weird thing is, they move on their own, I have not seen baby aiptasia do this, but a part of me doesn't know for sure, so I removed instantly. What are these?

Hard to tell with warm lighting but either aptasia or Hydroids. Im leaning at aptasia

Darn, that sucks. I gotta stay vigilant and be on the prowl daily! Luckily it's a brand new tank and not much nutrients to feast on.

Keep it simply. Using a syringe or pipette, 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
