He will follow me from side to side sometimes.
Especially if I have food getting ready to go in.
I put my shrimp on some of their water in a small plastic container to let it break up and he will come to the top and tap the glass right under the food.
He knows when hes getting his haha
My male will come up top for a pellet when I tap the glass. The female is a little slower to come up top..lol
