I bought a syrnige from petsmart used for medicating dogs for $4. I load the chamber with mysis and cyclopeeze. I'll feed my Duncan, and witht he food hitting the water my brittle will come wheeling outfrom under his rock, wrap an arm around the endof the syringe and catch some mysis that I squirt out for him. It's neat watching them eat. Also, I joy feed him once every week or 10 days.
