I have a 1.5 week old rainbow btw. It recently stopped moving around and stays perched out of a cave even at night. I've tried feeding it PE Mysis daily, turning off the pump and droping 3 - 4 whole mysis right onto it. The anemone kind of reacts to it, sometimes holds on, but usually doesn't do anything with them.
I give up and 15 minutes later I turn the pumps on and ALL the mysis floats away.
Is this normal?
This is a photo of it a few days ago. Since then it has fully come out.
