Just found out one of my mated pair of clowns jumped out of the tank and went to the great reef beyond. Since I'm new to the hobby I'm not sure if I should keep the water level within an eighth of an inch from the top as I have been doing. I have a canopy but nothing to contain jumping.
Also, will it be a problem to add another clown or should I be happy I still have one?
It is not a good feeling when I lose the life of a fish through ignorance!!
