I picked this guy up at Petco yesterday after seeing him there for 3 weeks. He laid at the bottom of his bowl and was so sad that I had to give him a good home. I did notice that when I got him in his knew home that he would bump into the glass and hit the plants so I thought he was blind at first. But then I got to thinking that with his really red eyes that the light might hurt him so I turned the light out tonight and watched him and he swam perfectly, he didn't bump into anything and he didn't hit the glass.
I included a few pictures of him and one of his home just for reference. Please note the light is off now. I didn't know that it hurt him.
