Some use pcv, some use other small plastic containers like pill containers or plastic Easter eggs. I used one of those plastic combo spoons/ tubes with dosage measurements that come with meds for kids. Drill holes just above the bottom large enough for the longnose and copperband butterfly noses but too small for the other fish. Put food in, hang in the tank with fishing line, and let the fish figure it out.
