I mix blood worms and brine shrimp on every 3rd day of feeding. I bought a surringe from cvs and I mix up the frozen shrimp and worms with some tank water, suck it up with the surringe, feed my guys on top, and then reach about halfway down and shoot some of the mix to my loaches, they come out of whatever hole they are in and eat it all up, when I feed them pellets, i soak the pellets in a little tank water so they sink right away, I then feed my other top to middle swimmers (so they dont steal everything), I then put the soaked pellets about 4 or 5 inches down, my loaches swim right out, take a pellet each, then go back in their hiding places with it. They will find a way to eat, even if you dont go as crazy as me, if they are not eating for sure, check your water
