Hi Tony,
Glad you're back. As you can tell we were having some fun with your post while you were gone.
Give us much information about your animal as you can. It looks like it is an anemone from you last post. What type/size anemone is it, what size tank is it in, what are your water parameters, what kind of lights, what are you feeding it, does it eat what you feed. The pooping is usually not a good sign. Was it sort of dark brown and REAL stringy?
Sticking to the live rock is a good sign.
Finally, how long have you had the tank set up and how long have you had the anemone and was it acting differently and then change or is this just the way he's been since you got him?
