hey all, thanks in advance. My condy moves alot. Sometimes he will just either "fall" or release himself from the rocks onto the sand but he gets back up and climbs well. He is on the glass now. I noticed what seemed like his tentacles or what not kind of "stuck" to the glass. He moved a bit over night and left behind this residue. Not sure if it zooanthia or something to worry or not worry about. Any insight?
