I found it funny so I thought I'd share. My thermometer (the common one with the green suction cup that sticks to the wall) has been unattached and floating around the top of the tank for a few days now. I looked at it one day and there was a snail on it going for a ride. Around and around it went (the thermometer itself spins on its axis while it zooms around the tank) What I thought really funny was the peppermint shrimp last night decided it was time for a ride and was going around the tank p I'm waiting to see if the cleaner shrimp takes a turn on it next before I attach it to the wall again.
