What I used to do was take one of those Joe's Juice aptasia syringes, cut an inch or so of airline tube then a rigid 3/16 tube and attach to the syringe. Then I would suck up a bit of mysis in it and I could target feed at the bottom of the tank no problem. Just force it out a bit and lightly touch each mouth and they would actually draw it in on their own. I guess I was using this on Acans more
