My tank has the usual 2 triangle cutout in the lid corners. However 1 of these corners is where my clownfish go to sleep of a night. This then causes issues as they end up getting spooked in the night and end up jumping out of the tank through the small hole. All water parameters are good and have noticed them jump when a loud noise happens near the tank. The only reason this ends up an issue as they sleep right in the corner and face the cutout. Really couldn't pick a worse place to sleep.
Is there anyway I could properly cover this cutout. I have placed my tank measuring cup over it but it won't cover the whole thing due to the cables going through that hole.
