What is this?

Hello still new and have had my tank up and running for two months now. I have no fish right now just some zoes and a pipe organ that are doing very well and I noticed this guy on my glass last night.

Hard to tell from the pics but those look like nudibranchs to me.

There is only one it's just the reflection in the glass and sorry for pic quality it's small and my kessil light makes it hard to focus. I noticed the tentacles would suck back into it on and off

If you can get a couple more pics that might help. If the tentacles retract then it could be an aptasia but I can't say for sure.

that's the best I can get for now I'm at work but can try to get some when I get home
