Hi guys, I have female betta who is frantically swimming/glass surfing and completely restless. At some points she almost propells herself out of the tank. This behavior began about 3 days ago. Since then she has had a 100% percent water change, change in color of the background of her tank, change in room lighting, and I added various things to try to distract her. Although she is eating very well, she is totally entranced by this swimming. Normally she would respond to and watch any activity in the room she is in. She is housed in a 2.5 gallon tank with heater (water temp is in the mid/high 70's). I have checked ammonia levels and all is good there. I have male in another identical tank setup and water source who has shown no change in behavior. Does anyone have any thoughts on this behavior?
Thanks, and Happy Easter to all.
