Fish Jumping

[SCUBA_STEVE]

I had a Chromis recently jump from my tank and I am looking at building a screen top for it. Does anyone know where a guy can find some clear 1/4" mesh around Edmonton (i've heard polypropylene mesh works well), or if anyone has any other ideas that would be great too. I would like to get something in place so I don't lose another fish.
Thanks,
Steve
