Anemone ID?

I cant for the life of me find anything that looks like it anywhere. It came with my LR from about 9 months ago, and is one of the few things to survive my brother in law taking care of the tank while i was in europe for a month. I couldnt get a great picture of it, but it stays in the shadows, has short thin tentacles with bulbs at the very end, it does not have many tentacles, they are all around the outer rim of the body. it hasnt ever really moved much or grown much. it usually keeps its tentacles flared out almost flat with its body. sorry the pictures isnt great, its hard to get a good shot of.

Thanks! After looking at pictures it does resemble a Pseudocorynactis corallimorph. It is larger than any pics i saw online and has fewer tentacles but the tentacles themselves are almost identical. if it isnt a Pseudocorynactis corallimorph then it is definitely a relative. thank you guys!
