Shrimp Feeding Platform

Simple shrimp feeding platform I modeled up so I can feed my shrimp without the snails taking over. Since it's suspended the shrimp can swim to it, snails are helpless and get the shrimp droppings It simply slides onto my tank lid which is glass pane about .15 inches or 2.6 mm. Please let me know if you think the platform should be bigger, longer stem, large clip/clamp
