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.

If you take some fine/extra fine sandpaper to one side (or both sides) of the acrylic divider(s), you should be able to make the divider opaque and block the betta's vision of it's neighbor. :bounce:

Krylon Fusion is fine. It's used on the SW side of the hobby extensively on white PVC fittings dangling in tanks until they coat over with coralline algae. Scuffing the acrylic as suggested should also serve the same purpose.
