even tho he seems healthy, he could very well be slowly starving. I would definitely buy that kit and let them spawn in your refugium or sump, if you don't have one, you might have to buy a kit more often. In the meantime I would try to get ahold of some mysis shrimp and while still frozen make some small shavings. Put the shavings in a small cup of tank water, siphon into a turkey baster, and squirt in the general area of the mandarin. Mandarins have very small mouths and its hard for them to eat the entire body of the shrimp.
