Rainbow, one of my bettas passed away this morning. :'( Today Rainbow Passed away. All yesterday he was having trouble swimming and getting to the surface for air. So I lowered his water and put a nice tall silk plant in for him to lay on. This morning I got up and checked on him. He was facing with his head down and his tail up. But not dead yet. I lowered his water so it was halfway and then used the net to help him over to the tall plant I had. He looked up and then just passed away.
