Jail Break

[Karsten]

Hello Reefers,

I have a problem. I have had my tank running for about 1.5 years now. My corals are growing, my fish are all getting along. Yesterday I came home and could not find my Blue Tang. Well she was dryed out on the floor. This one hurt. It is not the first jumper either. In less than two years I have had a bicolor blenny, O. Clown, and now my blue tang all hit the floor.

Is there some way to stop this? Do most of you cover your tanks? Is it just bad luck? any advice would help
