Cory is right. We had problems with tetras getting stuck or if we raised the arm high it would slide down the arm. Thats why we have the two angled tubes on the top. They are welded at the same angle as the tetra, 120 deg. We also made everything longer so that we could hold onto two tetras at the same time. The two tubes to make the triangle was actually thought up and done in Atl. It was to, you are correct, reduce swinging. It worked well enough.
