I've been putting off doing this for a while but this week my 6 line wrasse jumped to his death. I found him on the bracing when I got home from work. So I'm going to build a screen top. I looked at the local hardware stores and I only saw the screen material that you see next to the frames. Anybody know where to get the 1/4" clear mesh like BRS sells? Or something like it that isn't screen?
