The only one that's soley on pods is the mandarin everything else is been eating mysis for the past yr. Was hard to get them on mysis but lots of determination and it happened. But I added 3 bottles yesterday one in the fuge the rest in the rocks so they should start reproducing I add a bottle every other month. This is what I did on my old 72 mandarin and others are still fat. I used to have a nice male and they would mate when the lights stared going down it was really cool. He passed unfortunately.
