it is possible for fish to go thru netting, but better than covering tank with glass or plexi and blocking gas/oxygen exchange, plus they get dirty and block lightbut isn't it possible for the fish to jump AND get caught in the mesh? I'd rather go the safer route and use glass or some thicker acrylic.
So what did you come up with, or are you still letting the fish decide their own fate?I would prefer something like what EllieSuz did in the back of my canopy.
