Put in an individual small tupperware with the water from the tank, then put frozen brine shrimp in there and keep the shrimp moving, it may take a day or two, but mine wants to eat every night now. My wife is a nurse, and brought home a syringe, I removed the needle, and assach a piece of airline tubing to it, and put the tube in the tank, and keep the syringe out, usinf one hand to guide the tube and ont to push the plunger!
