Frozen brine and mysis sink if you turn off flow. That’s what mine eats.Do you have any specific frozen food options for the Mandarins? I've kept mine for a few years, but I am tired of making the bbs every day. When I first had them I was able to find frozen pods that sank, and they ate it fine, but now all the frozen pods float, so it is just wasted.
Does anyone have a frozen food option/brand that I can train them to? I need something that sinks.
