I've got a 10 gallon cycled tank with a betta, 4 corys and 6 rasbora in it. I recently added a mystery snail and i have noticed my betta hovering around him a lot, the snail is even afraid to come out of his shell. Why is my betta doing this? I know they can be bullies but my betta is normally more laid back, he's lived with the corys and rasbora for months and hasn't bullied any of them. Is there there anything I can do to make him back off the snail?
(and before you yell at me about overstocking, my ammonia and nitrites are zero, and my nitrates barely observed a color change all using liquid tests so I'm fine until the mystery snail grows bigger)
