Get a red gel cover for the light if possible. I know you can buy it in sheets, possibly from any theatrics store. This is how I've picked up colored gels in the past, then cut them down to size. You might even be able to find a red bulb.
I have a red cover for my flashlight I use to view my fish at night, so I use that to look at Sticky.
You also might want to consider creating a top somehow out of screen, even if it means having plexiglass on the outside as a frame, and screen in the middle. You need a way for heat/some humidity to escape still. Investing in an Exo-Terra glass terrarium (has a screen top) is a great idea for the future if you ever want to. Check out craigslist and other local classifieds, even post wanted ads for them. It's the best thing I bought.
You might be able to get some sort of thin metal and bend it to fit around the tank and glue it together, using it as a frame. Just a few ideas. I have no idea of anywhere that sells screen tops for bow fronts.
