Re: How are you picking up the tetras?

We haven't actually tried picking it up from the ground, but theoretically (the p-word that the drivers hate) we can do it. The cone helps to center the tetra, and ultimately, if we can get it over the tetra, we can grab it about nine times out of ten. Again, it's much more efficiant to have our H.P. do it, but s/he needs to be tall (I'm 6 feet tall and I need to lift the tetra over my head to get it where it needs to go)
