What do you guys use to keep fish from going down the drain? Currently I have eggcrate at the top of box and it make the box noisier due to the water building up and falling. Is there any other alternatives? I had two clowns, one went down the drain and the other I never found.
This was before I had the egg crate at the top. It was sitting in the box just above the downturned elbow that acts as the drain.
