Really bad idea. There is no way on earth a 10 gallon tank, no matter how well established can support a pod population that can keep a mandarin sustained long term. If it adapts to frozen and you can feed it several times a day (ie 3-4) and it is the only fish in your tank (other fish will out compete it for food), it might work, but once again not recommended. I had one in my 36 gallon and spent a few hundred on pods, had it adapt to frozen mysis and reef frenzy and it still starved to death in 3 months. The fact remains that if you have a full time job or go to school full time you will be hard pressed to keep it from starving. They have very short digestive tracts and need to feed almost constantly during the waking hours.
