It seems either the rays, my cat and or dogs got the ray. He is no where to be found. I think i'm going to get aro that is a little larger. My lfs thinks it was the ray. I did see the ray doing something and then when the ray moved there was a big crater in the sand. MY lfs said that's what happens when their eating something. It sucks the the aro is gone, but I'm glad it was eaten and didn't suffocate from jumping out of the tank. I cannot think of anything else.
I just got back from picking up frozen blood worms. One of the rays was swimming around, the other one hasn't really moved much. I dropped some blood worms in and covered the tank with a blanket to help keep it darker. There's a sliding door by the tank so some light gets through even with the blinds shut.
