Brown string inside bubble tip anemone

[An ngo]

Hi guys, I have a green bubble tip for a week in my tank. It seem pretty healthy and inflate all the time. However, i saw brown strings inside its tip. It is a sign of unhealthy or just its poop??

Well, it looks bleached, and under that lighting it's going to highlight things you would not see under normal daylight
Mysis a couple times a week will help regain health and color
