I purchased some LR and found this guy in one of the crevices. I don't think its an Aiptasia (sp?) but I could very easily be wrong. It is about the size of a half dollar and can move around but seems to enjoy his location already. In addition, he seems very active and when touched by a probe, he does curl and grab on quite strongly. The picture is a little blurry and I'm trying to get another clearer one when its fully open again. Basically, I'm trying to decide if I should get rid of him as a pest or just let him be. Thanks in advance for any and all opinions and solutions.
