Bkueter,
Try thawing the mysis in water from the tank. I’ve noticed if the mysis is cooler than the water or still slightly frozen it won’t sink. You should also try rinsing the mysis in fresh SW, keeps the oily film from the top of your tank.
Here’s what I do. Place the mysis in a small dish, add just enough SW to cover, let sit for 15-20 minutes. You’ll notice the mysis sinks to the bottom of the container. Rense( I use a standard 3 inch fish net for this, anything that is small enogh to go through the holes My Sh aren’t going to eat anyway) with fresh SW. Add enrichment to container and place mysis back in. Let sit for 10-15 minutes. Then I add more sw suck up in a turkey baster slowly add to feeding dish.
It took me some time to actually get my mysis to sink when I fist started. You may find a way that works better for you, just keep trying.
