Actually the plastic canvas has holes small enough where I really doubt a fish can tell what the other fish is on the other side. It'l break up the shape on the other side a lot. This is used as dividers all the time for bettas and it works fine.
The water flows through mostly unimpeded. I just need to reduce my filter's current by half with it all the way down with a plant or something. My female betta hangs out on the right side of the tank where the current is least. She's a great swimmer compared to my male betta and doesn't really struggle to swim past the filter, she just must hate it anyway. My male betta enjoys a bit of current if its in an isolated area. He will sneak up on the current until he hits it and does a quick tumble, he keeps doing it when he obviously knows where the current is. He's a strange cookie
