I have acrylic dividers that I made to divide a tank do I could get multiple male bettas. I've been told that the males may get over seeing eachother, but may end up biting their own tails. Another member suggested painting the dividers, is their any aquarium safe paint that I could use. I've heard of krylon fusion and was wondering if anyone gfs used it and it didn't kill their fish. It if their may be other alternatives to block the males from seeing eachother.
