I Have a 10g tank that is almost completely full of live plants. I have recently acquired 2 red cherry shrimp. In the 10g is a betta who I have noticed likes to chase the shrimp. The only cover in the tank is the plants, I have a small forest of Rotala Indica and java moss along with amazon swords and an aponogeton Longiplumostus. Should I look into maybe providing a cave of some kind for the shrimp to hide in to get away from the betta? Thanks.
