Today, I bought three ghost shrimp to put in my 3.5 gallon tank with my male betta. My betta constantly seems to be trying to swim away from them. He hasnt been relaxing in his plants like he normally does. Also, one of his favorite spots to lay was under his heater. Now, a shrimp always seems to drive him out. The betta does not seem aggressive at all. It seems like the shrimp are bothering him, and are always ganging up on him. They do not give him his space. Do you think that he will get used to them, or should I just take them out all together?
