What to cover tank with

[mayreee]

I have like 1 or two pretty large openings in the back of my tank (glass lid). I was wondering what I could cover these with to make sure none of my fish jump out. Everytime I can't find one of them I start freaking out

a piece of wood would work or even thin pieces of plastic
You could also just fill in the slots with stuff like a powerhead or a new filter

Most glass tops have a plastic strip that fits on the rear so you can cut it out for the filter and heater. One of my LFS has the stuff in 10 ft. lengths. Its like .25 a foot. Maybe yours can get it for you.

Thanks guys! I am silly. I just remembered I had the plastic strip you were talking about, bassnman. It was stored away. Thanks again
