this strange looking thing is underneath my condy anemone. It looked like my an enemy was trying to figure out if it could eat it… It also appears to be moving on its own… If it dropped a tentacle, does it shrink to 100th of its size? And keep moving? I’ve never seen anything like this before… Attempting to get it into an isolation box right now !! TIA! apologies using dictation and trying to remove it lol
