Ok, I can't find anything around where I live here that would work as a tank divider. So I was going to order some stuff of amazon that might work until I move back to Oregon and can put in a permanent divider.
So I will be ordering some black plastic canvas and some clear as well. Then I will have airline tube suction cups that I will zip tie to the canvas (I would sand down the sharp end!).
So I was thinking about using two sheets of it to make it a little more difficult for them to see each other (like cut both differently to fit). I would cut out little sections so that the canvas will still reach the side if the tank but that section would allow the suction cups to not fit as awkwardly.
Everything is plastic or that canvas stuff. I was also thinking of putting aquarium sealant over the zip ties to be extra safe.
Any feedback? I have absolutely no materials here so it's all coming from amazon.
