New betta fish and existing betta fish update

Hi, today I got a new betta fish. So far, I am happy with him. He is blowing plenty of bubbles. He swims against the walls. He consistently moves around. He looks around and seems intelligent.

Update on my existing fish -- well, as you have guessed, I have put him back in the cup. I poked at both of his eyes with a needle, but he can still see. I didn't completely take his eyesight out. I poked at his flesh with a needle, too. Right now, he's near the top of the water and breathing heavily. I had chased him around with a spoon. There's food right in front of him but he won't eat it. I think he is recovering now. He's flapping his fins. I'm thinking about filling the water to the top, putting the lid on, and seeing how long he can last. For now though, I think I'll let him live. I should add that he lost some fins, I guess from me chasing him around the tank with the spoon and such. But he's still alive. Let me give him time and see if his breathing calms down.

This new fish is really good. He's a good fish and I like him.
