The Olympic Pole Vault Clown Fish

[bothabear]

Hi all.
I need some advice.
I have a clown fish who likes hopping from the tank into the heater section behind the screen on my boyu tl550.
How can I stop this?
If I drop the water level any more it will expose the heater.

Please help....

silicone a plastic strip to the divider, that touches the hood
The overflow part, you can use one of the old type of hair combs

Is he being bullied by another fish?
