I found this thing in my tank last night. It seems to open up more at night when the actinics are on or the tank is completely dark. This morning I woke up and it was completely closed. It looks to be brownish in color and about the size of a quarter in diameter. The stalk is maybe an inch to an inch and a half. Here is the best pic I could get of it just before the actinics came on. It has a mouth in the center and its tenticals look white or clear with tiny black balls on the tips. Sorry about the not so great pics it is in a horrible spot. Thanks for the help
