Yup, checked all 3 chambers and they weren't back there... I'm guessing that the small green cromis starved because it wouldn't eat pellets and a hermit had a snack. I usually feed brine shrimp about 3 times a week, but sometimes I get really busy with school and work and just forget. Maybe thats what happened to the stripped blenny as well. No idea where the clownfish went though.
And they did not jump out of the tank? If they did not them I am wondering what is going on as losing 3 fish is somewhat unusual ... Are you sure there is no Mantis Shrimp in the tank ? I am just wondering what could have happened to them and whether there is something in the tank that attacks them during the night. Did you ever find any bodies?
