a whiff of grapeshot

it still looks upside down.
you may flip it over.

what kind of lights do you have,
and what kind of flow.
(what size tank as well)

you might place it on some rock so its foot can attach.

I agree, its upside down.

its actually right-side up
the lights are a four t-5 light fixture (two actinic, two 10k)
for flow i have a koralia 550gph + return pump/spray bar @200gph
tank size is a 39 gallon tall with 10 gallon sump

the light fixture's timer went out about a week ago and i put up a 4,000k strip light that came with the aquarium.

plus pieces of it's tentacle are falling off....

so you're using a standard strip light on a tank with a photosynthetic anemone in it. I would venture to say that's the problem there.

Also in that picture it does indeed look upside down. I see purple tipped green tentacles under the anemone which is a good indication of it's 'top' so to speak. If it's not upside down and it's tentacles have fallen off to give that appearance, then it's really in bad shape, but I also don't see the oral slit at the 'top' of it now.

I would agree with dread on that one. I made the mistake of getting an anemone when my tank was not ready for one and didn't have the lighting for it and it started looking and acting like yours in the picture, followed by disintegration a few days later. Anemone death is usually followed by a minor or even major tank crash due to toxins that they release.

Though unfortunate, something to consider.

i flipped it over to see the bottom and when i did the guts and more tentacles fell off. i replaced the lights but i think its too far gone. i read online about dead anemones crashing tanks so i decided to get rid of it. the other tank mates were more important to me and i didnt want to risk it.
