Partitioning a feeding area

[Robder]

Hey,

Is there a gadget that will allow me to partition a section of the surface area for feeding?

The pellets are often ending up getting sucked behind my 3d background and stuck in places like the filter area and internal brackets of my tank.

Any ideas?

You can make one. Join a piece of airline tubing into a circle. It will float.
