FYI goldfish are bad for turtles, they have tiasamain or however it's spelled and they are fatty, turtles and I believe fish get almost nothing from eating themThis is an awesome DIY tank divider. You think that is will hold against 4-5" long RES turtles? I'm planning to divide my 6' long tank into 2' for some goldfish and 4' for the turtles. And what was the cost of your awesome project?
