Rainbow Bubble Tip Anemone Shrinking and Neon Green Foot?

[WorldZY]

Hi There! I am brand new to Corals. I bought a Prime 16HD AI Light, I had my water tested by the LFS (Don't have exact numbers, Get a Salifert Test kit Mon.), Tank is about 6 months old.

I posted yesterday, because the little guy sucked himself onto a shell rather than the rock next to him lol. He completely sprouted out an our or 2 later as you can see in the pictures. My Question is... Today, I noticed it looks like the RBA shrunk to almost half it's size, the foot is turning almost neon green (Lines of Neon Green), the bottom half of the RBA's fingers are neon green as well. Is this normal to have? Is this what they do or should I be concerned? I been seeing different comments saying it is normal and they are normal in a few days, It is dying, etc.. I would like your thoughts and advice. I did watch it eat some shrimp yesterday. I have 2 pictures down below for you to see.


- The Bluer light picture was last night
- The whiter light picture was taken about 30 minutes ago.

Thank you all for the help! :)

BTAs can act in funny ways at times, make sure that he can’t get chewed up with an internal circulation pump.

As long as his foot is showing as healthy and it’s oral disc is not breaking down, the guy should be fine.

Best long haul advise:
Get some good test kits, including nitrates and phosphates, for success for you, and your livestock.

Learn how to use them like the back of your hand.

Also:
Rearech your livestock, before you buy.

Thank you so much! So the green coloration is good then? I really appreciate the advice.

He is far away from the pump as well!
