A sad day a new jorney

[King Turkey]

Today I came home to my fish tank and noticed my fist fish passed away. my beloved clown fish bob was found on the floor dry. he jumped to his death. I need a tank lid and I cannot find any. any suggestions? it is 36.5x19.25 40g tank I have a tunze 9004 in it so I need to cut what ever I get to fit.
on a lighter note after my wife cried about or clown fish I did get a replacement and thought you know what I like that coral ban shrimp and lawnmower blenny.
I do not know much about lawnmower blennies having never owned one. do they sleep on rocks in sand? I know they eat algae. are they normally shy. I would love to hear about the animal behavior more from experience. sorry long rant
