Long tentacle anemone

[Crystalbivens1]

Should I be concerned because I am? Last night the tentacle had its foot in the sand, I checked on him this morning and he has taken his foot out of the sand. I tried to feed him but he didn't seem interested. His tentacles are still full and his mouth is closed. Worried because I purchased this tank already set up about two months ago and I have never seen him take his foot out. Any help would be appreciated. Thank you

Was there always brown algae on the sand? I might be wrong but I think brown algae forms with high levels of nitrates...so maybe check nitrate levels?

Do not worry about feeding right now. He is just moving to a spot he likes. 99% of the time they don't like the spots we pick for them. Feeding when you first put them in the tank just stresses them. I never fed mine the ten years I had him in the tank. They get all they need from the lighting and water column. I personally don't think your lighting is enough. Usual stock lighting never is. They need high intensity lighting.

The brown algea is from it cycling, I purchased the tank already set up when I got it about two months ago that's where the anenome was, I have never seen him do this before which is why I'm so worried.

If that is a biocube does it have the regular hood lights? If so that is not near enough light for him. I have a biocube and had to move a bubble tip out because of the lighting.
