I've had my betta Kreacher for a few months now. I had already had a pair of snails from a previous tank, so when Kreacher moved in, he was immediately used to them. He pecked at them a few times but that was it. Now it seems like he has latched onto one of the snails. When the snail is close to the surface of the water, Kreacher rests on him. When the snail sleeps at the bottom of the tank, Kreacher is usually nearby, either keeping watch or sleeping on top of the snail. This morning, Kreacher woke up before the snail and bumped into its shell a few times to wake it up. Is this normal? Is Kreacher being territorial or friendly?
