This was not here last night. It popped out of the fiji live rock in a mater of 30 minutes or so. I looks like several pearl bells stuck together. Bright white. I have avoided putting my face directly above it. It does not appear to be intelligent and is not tracking my movements or trying to communicate with others outside the tank. I do however have a cat and was wondering if they can host alien life form through the incubation periods. PS don't buy the $99 HP camera. Thanks.
