I have a nerite snail for each betta... All three bettas attack anything else. Had to rehome Cory cats and they ate all the shrimp I put in within an hour... Apparently I have very aggressive fish. They like to watch the nerites but don't bite the eyes off like they did to the gold mystery snail...
1 Halfmoon "King" Betta (Leviathan) 1 "King" betta (Roku) and 1 Black Moor (Tui)
