I'm a new Betta Mom and suffered my first love loss of a Gold Rabbit Snail. I think he may have starved since he was very happy for a day and a half with the tank to himself. Max the Betta was introduced and by the 3rd day of sharing the tank, Henry the snail became withdrawn. I observed Max bullying him every time he made an attempt to eat his tablet or a piece of carefully washed spinach leaf.
I am grateful for this and a site for Bettas as I learn all there is to keeping a happy small ecosystem of wonder.
