i need help! when i went to check on my bobtails this morning, one of them was laying on the sand. it's body is white, but the eyes are clear (not cloudy) and it's not moving. i thought it might be dead, but when i pick it up the tenticles are moving. but when i put it down it just sinks to the bottom of the tank. although i think i know what the answer is, i guess i'm looking for someone else to say it. i've never been very good at dealing with these sort of things.
