We made a custom top to attempt the fish from jumping out of the tank. We lost a fish one time, his/her name was RJ. The wrasse found a small hole and jumped. We made two tops from 1/2' thick clear poly-board. Cut to length, cut the opening, placed a 1/8" groove around the perimeter, and installed the mesh.
Not the perfect job but it will work.
