About a week ago I rescued a Long Tentacle Anemone from my daughters bf 10gallon aquarium that he had just set up a week before that. I really never intended to keep a nem and my intentions were to take it to LFS that weekend. Well within a couple days it's color had come back and it was filling out, by the weekend it looked real good. I like it so decided to keep it. For most of a week it stayed in on spot with it's foot buried. Last night it moved to the glass and now tonight it's hanging upside down holding on to the glass with half it's foot. It's color is normal and the tentacles are all inflated but the side of the foot that isn't attached to glass has a huge bubble on it that inflates and deflates. I've been feeding it mussels and deli shrimp pieces every other day.
Params are: temp. 76.6*, sg 1.025, ammo 0, Nitrite 0, Nitrate 0, Alk 10 dKH, pH 8.2, Calcium 480, Magnesium 1340 mg/L

I seriously don't want this thing passing on in my tank, that's why I never intended to get one in the first place, but I got attached to it in a short time.

LTAs move around quite a bit till they find a spot they like. What do you have for lighting? It sounds like its trying to get closer to the lights. As long as there's no tear in the foot I wouldn't be too worried, when my LTA was moving around it inflaed and deflated its foot to move around.

Probably should mention that depth from fixture to substrate is only 16".

Anemones need strong light so I don't think that's an issue....I would just let it find a place that it likes and continue feeding it as normal.

yeah, don't think lighting is an issue. LTA's can be weird, mine has just shriveled up for a few days and decides to move for no reason a couple times in the ~3 years I've had it.
