I love mandarins and have a breeding pair. They are long lived, very beautiful fish that I have been keeping for many years but there is no reason to go broke feeding them as they are a pretty easy fish to take care of but require different methods than most fish.
Kermit is a little thin and IMO you are not feeding him correctly. I know you are spending more to feed him then your spouse but they can and will live fine on New Born Brine shrimp. But you can't just throw them in the water, you need to make a feeder. I would also eliminate those pellets and you can eliminate the Nutrimar if you feed correctly.
A mandarin needs to eat every few seconds and although Nutrimar is an excellent food, your mandarin will digest it in a few minutes and need something else.
I wrote a couple of articles on them if you are interested. Good luck, I love mandarins.
