Look around the tank on the floor, or on the crossbrace. Cleaner wrasses are notorious carpet surfers.
Most small wrasses are jumpers. If you want to keep wrasses, get you some eggcrate flourescent light fixture diffuser material and cut it to fit the lip inside your tank. It lets light in, and keeps the fish in the water unless they jump perfectly vertical.
That reminds me of a time that my sister in law said "Oh how cute, you bought the dog a crawdad chew toy". My blue crawdad got out of the tank and crawled over thirty feet into the kitchen. It was nearly a hairball by then. It took a week to recover but believe it or not, it survived.
I've had two jumpers since I set up my 120 six months ago. One was my painted fairy wrasse who died. Also my firefish jumped during a water change, was saved and recovered only to dissappear a month later. Sorry to hear about your loss. Thought Id share to let you know your not alone.
i came downstairs the next day after i couldnt find him and he was swimming around so idk where he was just hiding i guess i figured he wasnt in the tank when i put some mysis shrimp in the tank and hed didnt come and eat
