msjinkzd pretty much called it. I used a turkey baster for mine though the idea about a lid is nice since mine can't find the food that is right in front of it! Mostly I do frozen blood worms or flakes, he will eat either. He does occasionally snap at the ghost shrimp but I assume he thinks they are food. For the most part he hides in the gravel (he's the same color) or under the little bridge... unless the betta goes down there and kicks him out.
