I've had my beta/fighting fish, Sven, for 15 months now, and he has shared a tank with my nerite snails for about 10 of those months. He has never had a problem with them before, but now if one of the nerites is on the side of the glass he flares at it and bobs at it. The snail doesn't seem to notice or care but wondering why this is happening all of a sudden. Any thoughts??

Maybe he has come into his own now and has grown - thinks the entire tank is his space now. Is he actually nipping at the snails little antenna, or just posturing at him? As long as the betta isn't actually nipping at the snail and causing either damage or for the snail not to be able to come out and eat, it shouldn't be a problem.
